Whenever a creature attacks you or a planeswalker you control, put a -1/-1 counter on that creature.

Cards in graveyards, exile, and libraries lose all abilities and card types.

Whenever a creature you don't control dies, you gain 2 life.
Whenever you gain life, put that many +1/+1 counters on target creature you control.

Deathtouch
Whenever you lose life, you may cast target black noncreature card in your graveyard this turn. If it would be put into a graveyard from anywhere this turn, exile it instead.
Whenever you gain life for the first time each turn, create a 1/1 black Actor creature token.

The Oltenen Emissary is all colors.
You may pay {W}{U}{B}{R}{G} rather than pay the mana cost for spells that you cast. When you do, you may cast spells without paying their mana costs until end of turn.

Whenever The Resting Place deals combat damage to a player, you may return a creature card with mana value 3 or less from your graveyard to the battlefield.

Deathtouch, lifelink
At the beginning of combat on your turn, for each creature your opponents control, you may tap an untapped creature you control. If you do, those creatures fight each other.

Enspirit (As you cast this spell, you may exile a nonenchantment creature you control until this leaves the battlefield or fails to resolve. Reduce this spell's cost by the exiled card's mana value.)

{2}{B}, Exile a card from your graveyard: Tomb Creeper gets +2/+2 until end of turn.

Reach
You may have other creatures you control enter as a copy of any creature card in a graveyard with equal or lesser mana value.

Ward—{2}, Pay 2 life.
At the beginning of your end step, if a card was put into or left your graveyard this turn, put a +1/+1 counter on Tormentor of Graves.

Attacking creatures you control have deathtouch.

Trample
{4}{R}{R}: Tortle Tinkerer explores. This ability costs {1} less to activate for each artifact you control. (Reveal the top card of your library. Put it into your hand if it's a land. Otherwise, put a +1/+1 counter on this creature, then you may put that card in your graveyard.)

Trample

Trained Reptile gets +1/+1 for each enchantment you control.
Trained Reptile can't be blocked by creatures with power 2 or less.
