Mountain Giant stat change to 10/14
Warpath creatures in general and especially defense focused creatures need health-power distribution in favor of health, overwise this card is fine, Giant subtype feels out of place without any giants synergy and in current set makes this card a bit underwhelming.
Shamba cost down to 4
Before enrage activation, Shamba is vanilla 10/10 body for 5 in it current state, which forces you to activate it as soon as possible considering how inefficient 10/10 for 5 is. Investing 9 resources into one card with no protection against removal can lose you game by itself. Lowering his cost down to 4 makes him not critically bad if you can't risk activating enrage at that point in game and puts him more in line with Skraars young, Enraged Hulker and Elder Ape, all of which lack 2 stat point compared to vanilla creatures at same cost.
Eucalyptys cost up to 6, number of bears down to 3, all spawn in same zone of your choice.
This rebalancing makes Eucalyptys tree work more like haste, with Call of crusade working as charge for FD and Jinhai ambush working as Vigilance for DoD.
Tiger gain haste
In it current state Tiger is 6-7 stat points below 6 cost vanilla stat line His ability is decent, but unreliable and only good in offense, without haste and at 10 hp he is more likely to die before getting to attack. With haste costing exactly 1 resource and pricing his ability as 2 stat points Tiger will be more on curve.
Panda change to 3 cost 1/16 pay 3: enrage 4 on enrage swap stats.
While panda stats are decent already, especially with balance or Hermit buffs, it feels like it lack some impact, considering how it is just beast defense golem without reach. This change will allow more agressive play without getting balance and will add some flavor to the card. If you will get balance on it, you will be able to use this enrage as "heal" of sorts.
Genesis battlesuit can be played from hand as 3 cost +7/+7 add artificial subtype instead of playing it as creature
This card have effect of Secluded constructor in it, that change will allow you to use last part of Seluded constructor ability, way to give artificials "haste". 7/7 are on curve 3 cost haste creature stats.
GI spy stats up to 6/6
This card isn't playable in artificial tribal decks, nor is it useful for omnitron. This card have fun unreliable ability, but there is no reason for it be that much under curve.
Overcharged bot morale cost down to 4, stats up to 10/10
This change allows you to play bot as vanilla 4 cost on-curve creature without necesseity to pay atleast one additional card for it. It still would be way worse than splitter if you won't remove additional cards with it, but it won't be critically bad. Morale change puts it in line with most artificial creatures.
Symbiote prototype morale down to 4 add can't attack or block unless you have artifact and his current ability, stats up to 13/13
This change makes Symbiote creature you would only run in artifact centric decks as alternative to splitter and will give them early power boost they need to survive until omnitron.
EMP grenade purity down to 1
Like all GI sideboard tech cards this one should be available to all decks with GI splash.
Defense perimeter Ability change to Defense perimeter start with 5 charges on it, every time creature attacks you, lose 1 charge and deal 2 damage to it. Pay 2, Exhaust Defense perimeter and Human creature you control: Add 5 charges to defense perimeter(Maximum 10 charges). If defense perimeter have 0 charges sacrifice it.
This ability change gives defense perimeter immidiate effect on board an adds more of human-artifacts synergy.
Brute spawn cost down to 2, stats up to 2/5
5 health make this card survive turn 1 prioirty lightning blast, something what can break a lot of plans with no way to interrupt it.
Thunder apprentice Revert neff. Change to spell cards she provide to not do double damage to artificials.
Thunder apprentice have below curve 1 drop stats, to be worth playing you need to get atleast 2 blasts from her. Snowballing against GI player with no early defenses(Especially if you sniper his infected drone/support drone in command) is real concern, but problem lies not in spells themselv, but in how easily artificials die to lightning blast.
Verore Channeler add Pay 1, Exhaust Verore Channeler: Change target of buff
Makes Verore channeler a bit more versatile as support caster.
Overcharged bolt Damage up to 6 + 4x, deployed characters only
That change makes bolt decent removal without allowing for early command snipes. Currently there is little reason to run it over lightning blast.
Overcharged storm add Any characters you control that started the turn on the battlefield cannot be moved this turn.
Evaluating losses by your opponent is biggest part of conterplay for aoe board clears, it was pretty much constant for how battlefield aoe works, no reason for this card to not have that restriction.
Disctraction drone cost up to 2 Immune to combat damage while in assault. If it enters combat with another character move both to support.
This change makes disctraction drone true combat distraction, something annoying you have to remove first before dealing with opponent forces, right now it feels like delayed unreliable stumble with only benefit against haste and vigilance.
Ferocious flyer stats up to 8/4
Moves her more on curve as flying charge creature.
Noble Protector cost up to 5 stats up to 8/10 charge characters you control cannot take non combat damage turn he deployed.

Power of underdog cost up to 3 effect change to if target character in assault would die to combat damage this turn in assault he instead survives with 1 hp and his opponent dies.
