Ratadrabik of Urborg + Saw in Half + Mondrak, Glory Dominus + Bard, King of Dale

Ratadrabik of Urborg

Saw in Half

Mondrak, Glory Dominus

Bard, King of Dale

How it works

1. Cast Saw in Half by paying 2, destroying [[Increaser - Tokens$1]] and creating four token copies of it with base power equal to half the destroyed creature's power and base toughness equal to half the destroyed creature's toughness, rounding up each time.
2. Put all but one [[Increaser - Tokens$1]] token into your graveyard due to the legend rule.
3. Ratadrabik triggers four times from the nontoken and token [[Increaser - Tokens$1]]s dying.
4. Resolve the first trigger, creating 2^X nonlegendary token copies of [[Increaser - Tokens$1]] that are 2/2 Zombies, where X is the number of [[Increaser - Tokens$1]]s you control plus one.
5. Repeat step 4 for the remaining triggers.

This brilliant loop kicks off when you target a legendary token-doubling engine like Mondrak, Glory Dominus or Bard, King of Dale with Saw in Half, immediately cutting its stats in half and forcing the legend rule to send the duplicates straight to the graveyard. Because Ratadrabik of Urborg watches your legendary creatures perish, its static replacement effect triggers off these deaths to spawn fresh zombie copies. Thanks to Mondrak, Glory Dominus and Bard, King of Dale doubling your token generation whenever they're on the field, the resulting influx of token copies creates an exponential cascade. You end up with an unstoppable, near-infinite army of entering creatures and token copies that easily overwhelms your opponents.
