In terms of fun:
Circulus! This has to be one of my favorite 2 drops in the game, next to Ethereal Obelysk and Young Silithar. It gives so much card advantage at the cost of saturating your deck with 2/1 illusions. Like Silithar and Obelysk, this 2 drop generates value in unconventional ways and requires careful positioning to use effectively.
In terms of art:
Sirocco. Someone’s been skipping leg day ( ͡° ͜ʖ ͡°)
So is trinity wing good in classic spellhai? Or does spellhai just use arcanysts now?
Haven’t got to play with any of the cards since I’ve only unlocked 6 cards so far and the ones I have got need to be in decks with other cards from the set or are not outright good enough to see play by themselves. My favourite card from the set just from name alone is Godhammer, but a possible favourite ability-wise could be Grimes since I got fun ideas for that card in terms of repeated resurrections, which I’ll test at the start of next season if I get the card.
the card is so good i put arcanysts in my non spell themed sajj deck just so i could run it
well, it is a broken card. but it’s the ONLY unconditional removal vet has in a game where good removal is almost mandatory.
I would say thunderclap. “Borrowing” your opponents Juggernaut or Sunforge lancer feals so good. Blood of air would probably be a close second, but I don’t have it yet so I can’t comment on it.
Death Knell is great, it feels so powerful to just fill a 3x3 with powerful minions. My favorite has to be Trinity Wing though, it’s so versatile.
So far I’m having a lot of fun playing Rage Binder, I find it fun to see eggs hatch and give me health somehow.
I particularly appreciate Lavaslasher’s sprite, so it’s my favorite of the bunch.
Blood of air wins hand down
VET HAS RANGED REMOVAL!
My love is with the pair of Nightshroud and Death Knell due to them becoming a base for the whole new archetype.
However, if I have to choose only one card it’s definitely Blue Conjurer. A body, draw engine and more possibly strong board presence seems OP in combination, even if a little too slow.
Trinity Wing! Haven’t even played it, but love that design. That effect balanced with the Bond is just a great move.
Trinity Wing is pretty much strictly an arcanyst card. I have ~14 arcanysts in my deck (not counting Trinity Wing itself) and it’s still sometimes hard to get his effect activated. Not something you can easily play in any deck.
I forget his ability was a bond ability…lol.
I’d say my favorite card this expansion is either Circulus or Dream shaper, in both cases, they are cheap draw engines which I am a huge fan of and also do a lot to allow for new interesting lines of play and deck building opportunities
My fav card has to be celebrant. It takes one of the games most underused mechanics, and does something with it (no one misses you, mana burn). It isn’t broken, it isn’t trash, it synergizes, and takes skill to use right. 10/10 card in my book
I’m playing with Grimes currently in my Dying Wish build, just a cool card that also enables some swarmy tactics. I love to run cards that have a nice yet not too powerful effect, so the opponent has to actually give some thought whether or not he should waste a dispel on them.
Got a fun story with grimes. Had an arti Saji match against vanar ramping grimes. Funny, it summoned skyrock as OG and another cheap minion, which I don’t remember, when I killed it with thunderclap. In my hands, however, it summoned Dragonbone Golem. Opponent conceded instantly)
I liked because it’s fun but Grimes is the prime example of RNG bullshit nobody really wants.
… I want it 
I’m having a blast with Circulus. He is one of the most interesting and unique draw engines in the game and definitely my favourite!
