Putting subtle pressure on your opponents blocks (i.e., you can threaten to trade up your Malboro into Balamb T-Rexaur thanks to Paladin's Arms)
If the game is already limiting players to like-for-like swaps, the trading pool will already be severely limited
If the "intervening if" clause of Suppressor Skyguard's last ability is no longer met when the ability tries to resolve, it won't resolve and none of its effects will happen
This also sets up combos pretty well if you have what you need in your graveyard
These include Drake Hatcher (vigilance, prowess, creature tokens), Archmage of Runes (makes spells cheaper, draw), Mischievous Mystic (creature tokens), Clinquant Skymage (+1/+1 counters), and Micromancer (fetches a spell)
The MTG Marvel Spider-Man set will also see the return of five different Welcome Decks, a product we'd last seen in MTG Foundations
