Blitz Hellion

Seven power for five mana with trample and haste is a body well above the curve, and the end-step shuffle is the bill for it: you cast this, you swing for a guaranteed seven (overflow trampling through any chump block), then it vanishes back into a randomized library with no permanent footprint left behind. The design treats the creature as a recurring projectile rather than a board presence. It dodges sorcery-speed removal on your opponent's turn (it is gone before they untap), it never sticks around to feed a wrath or a reanimation spell, and it can be redrawn and fired again. The flip side is total: you pay full price for one attack and get nothing on defense, no follow-up, no presence the moment your turn ends. What makes the shuffle a puzzle rather than pure drawback is that the trigger is permanent and unconditional. It is not a one-time leaves-eventually clause you can flicker around; the ability fires at the beginning of every end step, so blinking the Hellion, phasing it, or skipping a single end step buys you exactly one more turn before the same trigger comes back due. There is no keeping it on the battlefield long-term short of removing the text itself. Built straight, it is a fragile haymaker that demands you win the turn it lands: the same line that prices the enormous body is the one a builder spends the most effort trying to delete.
