Calix, Guided by Fate | Three Blind Mice | Doubling Season

Cards

Deal combat damage to an opponent using
Calix.
Calix's second ability triggers, creating two token copies of
Three Blind Mice.
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, as well as
Calix's first ability twice.
Resolve both
Calix triggers, putting two +1/+1 counters on a creature you control.
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.
