Due to a rules change that takes effect with this release (see below for details), a Saga that somehow loses all of its chapter abilities will not be sacrificed as a state-based action
Based on the earlier theory, wave three of these cards will feature the starters hailing from Hoenn, Kalos, and Paldea
You have a 5 Life Purple leader with a better, auto-included, Onigashima in your leader
It gains indestructible until end of turn, (both if you pay two generic), and three generic plus double white adds Destroy all creatures. So, if we just want to look to Final Showdown as a board wipe, then this card costs three generic and triple white for an instant-speed Wrath of God
Since it requires the most experience, it has the best performance and evaluation
These are just some of the things I have picked up along the way that have worked for me
