Markov Blademaster

The runaway-snowball design taken to its logical extreme: double strike means the first connection deals two instances of combat damage and triggers the counter twice over, so a single unblocked attack vaults a 1/1 to a 3/3, then a 5/5 the turn after, then a 7/7. The counters and the double strike feed each other in a way that compounds faster than almost any other creature built on this template, because each new counter is multiplied across both damage steps the next time it swings. The catch is right there in the body: a 1/1 that dies to almost any removal spell before it ever connects, and whose counters vanish the moment it's gone, resetting the whole engine to zero. This is the bargain at the heart of the card. The payoff is enormous, but it requires that first hit to land naked, which means the work happens elsewhere: in evasion, in a way to force the block away, in protection that keeps the fragile frame alive through the turn it matters. On its own it is a glass cannon that announces exactly what it wants to do and dares the table to stop it before the math runs away. The reward curve is steep enough that the question is never whether the creature is good when it connects (it is overwhelming) but whether you can engineer the single window where it connects at all.
