Bitterblossom + Skrelvs Hive + Dreadhorde Invasion Skrelv's Hive and Dreadhorde Invasion iterate on the template Bitterblossom established
Any supplementary decks a player has (for example, an Attraction deck) also get shuffled and brought into the subgame
Fumigate is the best sweeper in the format
This ability not only lets you slowly take down your opponents strongest blockers, but it also works incredibly well with other decks like Yawgmoth, Thran Physician, which also spreads -1/-1 counters around for your benefit
If you don't already own at least one copy of the card you want to craft, choose Craft at the top right of the main deck building screen before you search for the card
Clamavus is an excellent follow up the turn after you cast Minsc & Boo, potentially making Boo with +1/+1 counters even larger than expected, perfect for flinging and drawing cards
