I have had Library in my unpowered drafting cube for nearing a year now and it has like a 40% win rate at best as a turn one play
This might sound stupid, but it is important to have settled on a deck in advance and practised as much as possible beforehand
It was actually protecting my graveyard from Deathrite Shaman that really sold me, even though its a pretty big corner case where that will matter
Its also very strong as a 2-mana draw two, an incredible rate made even better since you get the best two of three, a choice thats always better than two random cards
If you compare it to other decks (Water, Grass), fire has some limitations when it comes to powering up their attackers in an efficient way, let alone drawing cards
The other abilities are straight-up removal or reanimation, which includes planeswalker cards
