Trample When Thought Gorger enters, put a +1/+1 counter on it for each card in your hand. If you do, discard your hand. When Thought Gorger leaves the battlefield, draw a card for each +1/+1 counter on it.
If you control an Eldrazi Spawn, create three 0/1 colorless Eldrazi Spawn creature tokens. They have "Sacrifice this creature: Add {C}." Otherwise, create one of those tokens.
Flying When Conquering Manticore enters, gain control of target creature an opponent controls until end of turn. Untap that creature. It gains haste until end of turn.
As an additional cost to cast this spell, reveal a creature card from your hand. Disaster Radius deals X damage to each creature your opponents control, where X is the revealed card's mana value.
Choose any target. Reveal cards from the top of your library until you reveal a nonland card. Explosive Revelation deals damage equal to that card's mana value to that permanent or player. Put the nonland card into your hand and the rest on the bottom of your library in any order.
