Guardians of The Galaxy
Like Spider-Verse, GotG is all about amplifying this subdeck through several different interactions. However, while the former has multiple mechanisms for summoning new units, or turning fallen characters into weaker character cards as they fall in battle, GotG is more focused on permanently increasing stats through Victory states and by defeating other enemies in battle.
For example, the Star Lord card can grant +3 Strength to all characters every time a GotG unit defeats an enemy. Meanwhile, Mantis has a similar effect, but only benefits the units that defeat the enemy. Another important card here is Ego, which permanently absorbs the basic Power and Armor of any unit he defeats and can snowball into one of the strongest cards if used properly.
