Which hero to replace? Just got SM, HB, Anubis, Molt, DD, Revenant and 2 LN.

Just bought the bazaar pack and spent 28k on rolls. The more notable ones are Anubis, 2 Lil Nicks, Revenant. No Trixie and Michael though... had 2 Michael at smurf by casually rolling. Got Moltanica in 12 tries of treasure chest, Dread Drake in prime hero card.

So question is who to replace with who?

Current heroes: 200EE SK, 200 EE PD, 180 EE Vlad, 182 E SB, 182 E Cupid, 176 Ghoulem. Stuck in ID 2-4, sweeping ID1. HBM S-4, HT L18.

New heroes: Heartbreaker, Lil Nick, Spirit Mage, Anubis, Dread Drake, Moltanica, Revenant.
