Phantom Beast

The drawback rewrites the math of every removal spell aimed its way, and the math runs against the Beast. A 4/5 for four is a genuine body, large enough to dominate a stalled board and outclass most of what shows up across the table early. But the sacrifice clause means it cannot be answered, only erased: any Doom Blade, any pump spell, any tap effect, any targeted ability of any kind sends it to the graveyard, and the cheaper that interaction, the better the trade for your opponent. A repeatable pinger that only needs to point at it once gets the Beast for nothing. The clause is colorblind, which is the cruel part. You cannot protect it with an aura, cannot bolster it with your own Giant Growth, cannot bounce it to save it from a worse fate, because every one of those spells targets, and targeting is the trigger. This is the illusion bargain in its starkest form: an oversized creature that demands to be raced rather than answered, paid for by a fragility so total that the body never gets to matter once a single spell is pointed its way. It plays less like a threat than a dare. If the opponent is holding spot removal, the Beast dies the instant they use it; if they are not, it is a clock they have to chump or outrun.
