Muldrotha, the Gravetide + Displacer Kitten + Sol Ring + Megatog

4-card combo · UBRG

Verdict

Yes — this 4-card loop grows Megatog to an arbitrarily large attacker while generating infinite ETB and LTB triggers off Muldrotha's graveyard-cast permission refreshing each blink.

Sol Ring sacrifices to Megatog's activated ability for +3/+3, then Muldrotha replays it from the graveyard for 1; casting an artifact spell triggers Displacer Kitten, which blinks Muldrotha and resets the once-per-turn artifact cast restriction. The engine sits in a UBRG shell — Muldrotha graveyard decks are the natural home since every piece either fills or benefits from a stocked bin.

Recipe

Activate Sol Ring by tapping it, adding .
Activate Megatog by sacrificing Sol Ring, giving Megatog +3/+3 until end of turn.
Cast Sol Ring from your graveyard by paying .
Displacer Kitten triggers, blinking Muldrotha.
Repeat.

Result

Infinite ETB; Infinite LTB; Infinitely large creature until end of turn; Infinite storm count

Variations

Cheaper, tighter, alternate lines

Any artifact that costs 1 or less and produces mana on the same axis as Sol Ring can substitute — Mana Crypt skips the mana-neutral problem but the sacrifice-and-recast loop is the same. Megatog needs a swing to convert the size into a kill; if the table has blockers, pair the loop with Altar of Dementia or a free sacrifice outlet that converts infinite death triggers into a mill win instead.
