Pucas Mischief is a pretty much unknown card that often creates hilarious game states

If you somehow control Phenomenon Investigators and no choice was made for it (perhaps because another permanent on the battlefield became a copy of it, or it was manifested and later turned face up), it has neither of the two triggered abilities, no matter how much you want to believe (or doubt)

One of these rumors is that Modern Horizons II has a new cycle of no mana cost suspend spells in the vein of Crashing Footfalls, Restore Balance and Living End

That is a little too much for a targetted discard card at two mana

And her five color capacity is often a boon

Individual cards from these sets will continue to be legal in any format in which they are already legal
