Archon Summon 2

Flying just above the fray, the archon sent gusts of wind through the hordes of satyrs, sweeping them over the edge of the battleground and clearing a path to Xenagos. The Satyr-God sent a barrage of fireballs as Elspeth and Ajani approached. He ripped huge slabs of marble from the ground, set them alight, and launched the fiery rocks into the midst of the celestial army. The archon dodged the flaming projectiles and made a frontal assault at Xenagos. He sliced his blade across Xenagos’s neck. The blade cut through immaterial flesh, and Xenagos wasn’t harmed. The archon prepared another assault, but a massive rock slammed into his winged mount. The archon vanished in a burst of light, but before it dissipated, it imparted Elspeth with its inhuman strength and speed.
