Ruination Wurm

No abilities, no evasion, no enters-the-battlefield clause: a 7/6 with a blank text box is built to do exactly one thing on the ground, which is be larger than whatever blocks it. The Gruul colors and the raw size aim the card at a job a long line of vanilla fatties has filled: trade up in combat, demand a removal spell, and finish once the board stalls. The honest reading of the rate is that you are paying for stats and accepting that stats alone are what you get. Designs like this are the floor against which creatures with text get priced, the reference point that lets a developer call a four-mana 4/4 with a relevant ability a fair deal. The body sits near the top of a midrange curve where a deck wants one more threat that has to be answered, and it asks nothing of the pilot beyond casting it and swinging. That narrowness is the whole identity: a creature with no decisions attached, occupying the spot where a deck needs mass and nothing more.
