MTG Combo: Felidar Guardian + Mirror March

Requires winning that initial flip, unless you had two creatures that blinked other creatures. Each copy you make targets the first Felidar Guardian, netting you potentially a very large quantity of Felidar Guardians. Note that for each group of tokens generated for each batch of coins flipped from Mirror March, only one blink ability can resolve on one target at a time, so all the other token etbs need to target other things, either other nontoken creatures for more Mirror March triggers, or the lands to play more spells.
