Combos Utilizing Defense-of-the-Heart

Use doth to get avatars, use replenish to get doth back, repeat

Bring out a buff 6/6 double-strike and copy it in one turn.

use the doth to bring out the polar kraken and then sacrifice it to the spawning bed

.

first, play the recurring nightmare and defense of the heart. then, play the coat of arms and wait for the three creatures. finaly, sac the defense of the heart and get 2 hermits out and be all set.

play the defense, and during the begging of your turn play natuaral affinity, so if your opponet doesn't have 3 creautes, his lands will support your defense.

Get Monk Idealist and another Creature out with Defense of the Heart, then get Defense back again with the Monk Idealist and, possibly, play it out again.

When your oppenent has 3 or more creatures, beat him down. Demonic idea.

It is a basic combo but still it is quick and easy because you need so little mana.

Play Defense and get a Monk and something else. Return the Defense to your hand and replay it doing the same thing again. When there arent Monks left in your deck kill them, play Repopulate and repeat
