This is where my list is at currently: Creatures (6) Planeswalkers (3) Lands (26) Spells (25) This list is inspired by playing games with control decks Id built before against Andrew Cuneo and learning from the ways in which he smashed me
There are two kinds of Magic Academy events, each themed around different parts of the learning process
This, however, is not the main reason the card is so expensive
Not because there is a hard limit as such, but because I dont really play Modern anymore
My decklist was probably a little unfocused as I dont enjoy playing Dimir control in Commander (you end up the archenemy every game, and without cards like Rhystic Study, its hard to get to your end game)
If this happens, not only does the chapter ability you landed on trigger, but any ones you passed along the way
