Simple answer: yes, yes you can play more than the minimum deck size
Duh only cares if the card it's targeting has reminder text
If a player suspends a card with a high mana cost, the game will look entirely different by the time it can be cast
The changes proposed here are to improve the card quality, taking out a Forest since this deck doesnt need 25 lands, and bad cards like Wildwood Patrol to add strong uncommons and rares that make this game plan much more consistent
Like most Magic: The Gathering cards, the value of Ancestral Anger depends on a few consistent factors: its rarity, the printing and finish (regular or foil), its physical condition, and the set it was printed in (Innistrad: Double Feature)
Some of these are much better than others, but all are at the very least decent when theyre transformed
