Electrodominance Effects that let you play a card without paying its mana cost have a high potential to be broken, and there are a bunch of cards with suspend that can be exploited this way
A Holiday for Some, a Bombshell for All Ill be honest, the vibe in Standard has been pretty grim lately
It would need to be a tempo deck with card advantage and/or quality in reasonable abundance that still had sufficient room for reactive non-specific disruption
You might still be able to eke out a win every now and then, but I think this deck probably belongs at mid-to-high power tables, not high-to-cEDH
We keep things Commander-focused, though you bet some Constructed all-stars will make an appearance too
If you do, add an amount of R equal to the sacrificed creatures power
