Dull, low powered cards that replace themselves allow you to pad out your deck thus increasing the consistency of getting your key cards and ensuring you have lands and stuff going on as well
Thornling When Thornling came out, it seemed like a really awesome card
#19 i don't really see revavroom ex being viable (pretty mid attack, has an ability that isn't splashable) BUT attaching four of those +30 HP tool cards on it will be funny it also synergizes with the base set revavroom so theres still hope even if the bar is super low for this set on a competitive level, it at least is a step above most ex's in this set That what I was thinking, but sadly big Charms r out of rotation being they r from SWORD AND SHIELD, but there could of been a reprint
And just for noncombat damage, like Lightning Bolt or tapping that Kamahl, Pit Fighter for three damage too
I dont have a tuned list of this deck, but you have to plan on being combo-focused if you want it to be good
