Surtland Flinger

A sacrifice-for-damage attack trigger with a rider that quietly changes what you want to feed it. The base mode is a Fling stapled to combat: whenever this attacks, you convert one of your own creatures into a bolt for its power. The Giant clause is the reason to run this over a generic throw-a-creature outlet, because sacrificing a Giant doubles the damage, so even a modest tribal body lands like a burn spell twice its printed size. That doubling turns the ability into a payoff for a critical mass you had to build toward rather than a single expensive sacrifice, and it rewards committing to a type instead of hunting for one fat target. The sequencing is the interesting part, and it cuts against you as often as for you. The trigger fires on attack, before blockers are declared, so you are throwing a creature and pointing the damage while your opponent still holds all their combat decisions. Spend a blocker's future value now and they may simply block the 4/6 anyway; hold the ammunition and you lose the reach entirely. Each throw trades a permanent for a one-shot at incomplete information, which makes the 4/6 body less a beater than a durable delivery mechanism: it survives to attack again and again while the rest of your board becomes disposable ordnance. It is an outlet and a reach engine in one slot, most dangerous when your creatures were always meant to die and inert when nothing on the board is worth spending.
