To participate in solo battles, you will need to use Event Stamina
But the real challenge comes in finding ways to use those Zombies for other, more sacrificial means
Master Duel can be powerful tools to have on your side when you have the proper deck to work with
If you dont already have the cards from sets between SWSH Base Set to Fusion Strike (especially the stamped Gengar and Mew cards) for your personal/species collections, make sure to pick them up sooner than later
The deck includes 60 unique cards, 11 damage counters, a paper playmat, a tracker token, a Quick Start Rules sheet, and a bonus booster pack of 12 randomized cards
Plus, you can threaten your opponents creatures with removal if they block a band with enough power to destroy the creature and more toughness than the blocker has power
