Processing was the Eldrazi mechanic that asked you to play both sides of the exile zone: opponents' cards had to already be sitting in exile before this body could do anything, and the cast trigger pays you for shoveling two of them into graveyards. That dependency is the whole design tension. On its own, a 4/5 for five is a fine but unremarkable wall; the moment a Wasteland Strangler, a Brutal Expulsion, or any ingest creature has banked fuel in exile, casting this becomes a tempo spike that builds a small Eldrazi board out of nothing. Three Scion tokens that each crack for colorless mana turn the value into ramp, sacrifice fodder, or chump blockers, which is why the card reads less like a midrange beater and more like the payoff end of an engine. The structural wrinkle is that processing inverts what exile usually means: ingest and similar effects bury an opponent's material in the most inaccessible zone in the game, and this card chooses to surrender that permanence, returning two of those cards to graveyards where they could be recurred. You pay back a sliver of denial in exchange for a board, and the trade is worth it because the Scions arrive at the same time. It rewards a deck committed to the exile-matters axis rather than splashing it, and it falls flat anywhere that axis is absent, which is the honest cost of building a creature around a zone most decks never touch.
