Mire Triton

Three abilities a black deck wants, bundled onto one two-drop for the price of admission. The deathtouch turns a fragile body into a creature that trades up or holds a chokepoint against anything foolish enough to attack into it; the two life buys a couple of turns against aggression; and the self-mill feeds any graveyard the deck is trying to build. That last clause is the one that changes what kind of card this is. Read as a pure blocker, it is a modest speed bump. Read as an enabler, milling two into your own yard is exactly the payload for reanimation, delve, threshold, or any effect that counts cards in the graveyard, and it does that work while still leaving a real creature on the board. The design tension is that no single line here is above rate: a 2/1 deathtoucher, a two-point lifegain, a two-card mill would each be filler on their own. Stapling them together makes a card that quietly satisfies three different deckbuilding checkboxes at once, which is why it shows up in decks that never asked for a blocker at all. The self-mill is close to free when the yard is inert (barring a game that goes to fatigue, the two random cards were not resources you were counting on), which is exactly why the card rewards being built around: the same clause that costs nothing in a fair deck becomes the whole point in a graveyard deck.
