As for Armored Ascension, its not the first of its kind to reward mono-color decks, but I wanted to highlight it here as part of this focus on color-based restrictions
The core tactic of this deck is to create lots of tokens, which we can hopefully can do with the likes of Anointed Procession, Doubling Season, Parallel Lives and Primal Vigor
Instant Color tag templates(None) Adamant Will Target creature gets +2/+2 and gains indestructible until end of turn
Fifty rares I can get $3 for, that's another $150 so we're up to $310
While this can be a little dangerous (especially against Phelddagrif decks), you can harness this effect to enable some extra mana for cards like Vampiric Tutor, Entomb, Infernal Grasp, or Village Rites while still tapping all your lands on your turn
All this is after youve forced them to discard at least three cards over the past few turns
