Combos Utilizing Deathcoil-Wurm

you play nantuko and the wurm then you use nantuko's ability on deathcoil so deathcoil becomes a 14/12 and attack for a definite 14 damage

Since Deathcoil Wurm can get past it's blocker, you make it an 11/10 until end of turn. That menas that your oppenent loses 11 life, and Deathcoil Wurm can only be defeated by a creature that has 10.

after you summon deathcoil wurm, cast lure and venom. if you happen to have enough mana, pump as much +x+x into howl from beyond as you can. all of their creatures that attempt to block die.

have the 3 urza's lands in play (mine,tower,power plant) with overgrowth on one of them. tap urza's lands and cast deathcoil wurm
