Oona's Blackguard

The Rogue tribe spent most of its early life as a keyword pun (unblockable bodies that wanted you to play few creatures, a contradiction that never resolved into a coherent deck) and this 1/1 flyer is the piece that flips it into an aggressive counters-and-discard engine instead. The two abilities are built to compound: every Rogue you deploy lands oversized by a counter, and any counter-bearing creature that connects strips a card from the defending player's hand. Stack a few Rogues and the discard stops being incidental and becomes the win condition: you are not racing the opponent's life total so much as emptying their hand a card per unblocked attacker per turn, which is a fundamentally different clock than a creature deck usually runs. The wrinkle is that the discard trigger reads "creature you control with a +1/+1 counter," not "Rogue," so the anthem and the payoff are technically decoupled. Any source of counters (proliferate, an outside +1/+1 effect, a graft creature) turns a non-Rogue into a discard engine too, which widens the build well past tribal lines. The body itself is the obvious liability: a 1/1 with no counter of its own dies to everything and gives back nothing if it does, so the whole structure leans on protecting a fragile lord long enough for the second and third Rogues to land. It is a lord whose value is entirely in what it does to the cards the opponent never gets to cast.
