Combos Utilizing Overtaker

Pay 3U and tap Overtaker. Untap Leviathan instead of having to sacrifice 2 islands.

with six available mana (at least 3 u) you may take control of an opponents creature with overtaker, make its creature type wizard with the imagecrafter and sac it to the voidmage to counter spell

Enchant a creature with shackles...untap and steal it with Overtaker...give it back tapped (doesn't untap during opponent's turn...or pump with Puffer to kill it...shackles comes back to your hand.

Grab a creature with Overtaker and destroy it with Rats of Rath and repeat. Demonic idea.

take over their creatures with overtaker, and then attack with them, then sacrifice them to bloodshot cyclopse and deal damage = to their power

Use Overtaker to take opponent's creature...use helm of possession to sacrifice it and grab another. (Use Skull Catapult for TypeII)

Take a creature fro opponent and attack with it,then sac it to High Market and gain 1 life.

Discard Squee for the spellshaper's ability and he can be brought back! It wouldn't let me write any spellshaper in card 2's slot so I wrote Overtaker. Of course this combo works with all spellshapers

play witch engine and overtaker, when you tap and use witch engine for mana, take it back with overtaker.

sac squee for overtaker and keep taking their creatures & sacing them for contamination then use the tockens from breeding pit when their creaures run out. ONLY USE AGAINST NON BLACK DECKS!!!!!!!!!!
