I had a good life gain angels deck before the last rotation that i really enjoyed

My favorite tribal decks before I took my EDH decks apart were vampires and dragons. Vampires for the aesthetic + flavor and having enough to go deep on the tribal theme. Dragons because who doesn't want to whirlwind slam a deck full of fatties?

I used to love Vampires in Ixalan Standard when Arena was new.

So I got a soft spot for those

Really loving hydras. Enjoyed every game I every played with it. It's lead by Magus Lucea Kane so it revolves around copying x spells. Most of the spells are also playable at any turn, you get both the early game board presence and big lethal threats in the end. I switched from Zaxara as the commander as Lucea that copies instead of just making x/x tokens but it enables huge Banefires and Crackle with power. Lots of fun for everyone basically.

I'm stuck on Demons. It's challenging to keep the mana curve to a manageable level but otherwise finding it fun to play especially after the Warhammer 40k set added some additional choices.
