Let me give you and basically everyone else the rundown both me and death pointed out (personally i sick of writing it again and again everytime someone get tilted for not packing heal or removel in hand)
Aggro faie lives on one card - mentor (which drop on 4 mana regardless to ramp) which you can remove in a second (3 removel you need to pack) and should.
Hearth sister is a good card but it is not a good removel paying 3 to place 2 dmg is not that good and does not remove much unless you go face.
Crypto in vanar is good yet every other general is better with it removel wise or synergy wise.
Lilith can pour hell with her crypto bbs and a cheap spell, meahv drops 8/8 stats on board with the cost of life she will get back gurenteed and so on also feeds trail.
Brome stall, get zeal suppost, feeds trail, ziran need no words, argeon - kinda meh (results in +2 dmg pretty similer to faie).
Zirix - dervish support all around.
Sajj - meh but a good clear
Kara - ok.
Ilena - the best single target removel in game with guantlet.
Reva - … need no words.
Shidai - …the same.
Kaleos - usefull.
Rag - still no words.
Starhorn - mill support
Vaath - smash support.
Now faie - gives 4 dmg to general - nothing else if you play right, i don’t see the opness.
Take every general mentioned above and give them crypto half of them will do better then faie in game and burn you faster.
Faie’s bbs has no in faction synergy - which is the reason why even if an expansion hits nothing will happen regarding faie.
Let’s talk about the dmg - your bbs comes up once in two turns, which means - you drop 1 dmg every turn.
With 3 crypto and 3 mentor you still get less dmg the reva can pull of or rag or cass.
The bbs upset you? Then let’s make it into a card and give vanar more out oc hand dmg because this is the only source where other factions got tons.
You have a way to avoid dmg - heal, place 3 mystics in deck and that’s it (6hp) or 3 azure (9hp).
If you’re running control you either run heal or run stall to win con (or both).
If you run no removel and no heal - then it is your problem, simple as that.
Faie’s bbs is ok for every reason around the board, if you still feel like it is op - build your best aggro faie deck and challenge those here who run aggro decks, you’ll be suprised.
