Death-Greeter's Champion

Backup normally hands out a keyword by copying it onto whatever creature the +1/+1 counter lands on, but the wording carves out an exception: point the counter at the source itself and it simply keeps its own abilities rather than granting them elsewhere. That clause is the whole engine, because the keyword being passed around is double strike. Aim Backup at another attacker and you hand out doubled damage plus a permanent counter for a turn; keep it on the Champion and you have a 3/2 double striker of your own, six damage on an unblocked swing. Dash stacks a third mode on top: cast it that way and it enters with haste, connects for double strike, then returns to your hand before it can be answered at sorcery speed or gang-blocked with impunity next turn. Read together, the three keywords describe one creature that plays as a one-shot combat amplifier, a permanent threat, or a hit-and-run finisher depending on how much mana is open and where the counter does the most work. Fragility is what pays for the aggression: a single point of base toughness means the counter it distributes is often the margin between the recipient surviving a block and dying to it, so every cast poses the same question of whether the +1/+1 is better spent shoring up a body or amplifying an attack. It is a compact study in how one shared keyword changes value entirely based on where it is pointed.
