fox mtg cards MTGNexus Mint / near mint condition trading card Magic the Gathering [098] INNISTRAD

Doing that twice per turn can completely swing games in your favor

If you have Academy Manufactor on the field, then you also create a Treasure Token and a Food Token every time you investigate, leading to endless ETBs, endless LTBs, endless Clue, Treasure, and Food Tokens, infinite lifegain, infinite card draw, infinite draw triggers, and infinite mana

A great card can be worth a decent amount even if it's printed at common rarity, while a super rare one that nobody wants to play could be worth significantly less

This spell is even better in self-mill decks where you can treat your graveyard as a secondary library

There are still multiple decks using Tolarian Academy to great effect
