Bright-Palm, Soul Awakener

Backup already reads as an aggressive twist on the enters-with-a-counter template: point the counter at a teammate and lend them the attack trigger, or keep it on the Fox itself and get a bigger swinger. What makes this build of the mechanic worth attention is the exponential math it hands off. The attack trigger doesn't add a counter, it doubles them. One counter becomes two, two become four, four become eight, and because Backup can seed the first counter onto whichever creature you want, the doubling engine can live on a body that would otherwise never earn removal. The evasion clause is the part that stops this from being a slow grind: a creature that can't be blocked by anything with power 2 or less walks past the exact wall of small blockers a counter-based aggro board tends to run into. So the card resolves a familiar tension in +1/+1-counter strategies, that going wide with small creatures and going tall on one threat usually pull against each other, by making the tall threat also unblockable by the small stuff. It is a payoff that scales geometrically on a curve where most counter payoffs scale by ones, and the Backup framing means it starts paying the turn it lands rather than asking for a full board first.
