Florian can dig super dip with his ability in this deck
If you have more than one commander (thanks to a partner ability, for example), controlling one of them when you finish casting Ancestral Communion is enough to satisfy the trigger condition of Ancestral Communion's first ability
Might as well rack up some scry triggers for free when they do
You get to draw an extra card, re-spend all your mana, and get an extra combat stepnot to mention extra upkeep/end step triggers, planeswalker activations, and so on
This strategy enables the introduction of high-power gameplay experiences without permanently impacting the digital card economy or the value of their physical counterparts
