({2} magic symbol) ({W} magic symbol) ({B} magic symbol) ({G} magic symbol) plus enough mana to pay for commander tax, if applicable available.
Steps
Cast
Anikthea either from your hand or from the command zone by paying ({2} magic symbol) ({W} magic symbol) ({B} magic symbol) ({G} magic symbol) and commander tax, if applicable.
When
Anikthea enters the battlefield, it triggers, exiling
Three Blind Mice from your graveyard and creating two token copies of it that are 3/3 Zombies in addition to their other types.
The
Three Blind Mice tokens enter the battlefield with two lore counters on them due to
Doubling Season, triggering their first and second chapter abilities.
Resolve the first
Three Blind Mice triggers, creating four 1/1 Mouse creature tokens.
Resolve the next
Three Blind Mice trigger, creating two token copies of a
Three Blind Mice token.
Repeat from step 3.
Once you have infinite
Three Blind Mice triggers, you may use them to copy any token(s) you control.
