However, Runic Armasaur does require your opponents to be running specific cards -- creatures and lands that have activated abilities that aren't mana abilities -- which contributes to its inconsistency
To strengthen things up, it partners with Zndrsplt, Eye of Wisdom, another coin-flipping card and solid chaos commander
This midrange strategy can build up slowly or explode into massive turns when the pieces come together
Many of the most powerful cards can be from years, even decades ago
Then, when its not your turn, how do enchantress and zombies and tokens decks, etc
These also are just great 1-drops that have impact early, and if you don't need to swap them, they can be utilized for card advantage - the map token and Hopeless Nightmare's sacrifice ability both help you see more cards
