Ratadrabik of Urborg + Vesuvan Duplimancy + Mondrak, Glory Dominus + Cackling Counterpart

Ratadrabik of Urborg

Vesuvan Duplimancy

Mondrak, Glory Dominus

Cackling Counterpart

How it works

1. Cast Cackling Counterpart by paying 1, targeting Mondrak.
2. Vesuvan Duplimancy triggers, creating two nonlegendary token copies of Mondrak.
3. Resolve Cackling Counterpart, creating eight copies of Mondrak.
4. Put all but one legendary Mondrak into your graveyard due to the legend rule.
5. When the Mondraks die, Ratadrabik triggers eight times.
6. Resolve the first Ratadrabik trigger, creating a number of nonlegendary token copies of Mondrak equal to 2^(the number of Mondraks you currently control) that are 2/2 Zombies in addition to their other types.
7. Repeat step 6 for each remaining trigger.
