Always enjoy another players rankings! I don't have Brenn, Desolation, Palifala, or Hemling maxed yet so that tells you what I think of them lol. I've been using Craniax more and more to stop ulunds and your #1 guy Graybrow from coming back, he also stops tofu scavenge and venka trample so he has turned a decent amount of battles in my favor. My favorite play is to use cavewise + giraffe + craniax which gives you a huge advantage over an enemy with Greybrow.
I don't have warwall, songale, molten elemental, aranduriel, or folen maxed. Glad you came around to the Sentinel in S tier!
Looks like I disagree the most with your rares. Thraghun isn't an all the time card but he crushes in archery only matches. Surprised about flame for hire, he just fits perfectly with lorkus and next to Craniax in the back, I like him a little more than the Shiek because of void doing better against Keelan when it gets to that point but with Shiek you can give something else life leach so I get it.
Forked tongue is A for me, though it sounds like he's close for you too.
I have Venomancer in C tier but maybe I need to look into how you're comboing it. I've been using Buttercup Mauler more as a counter to venka in the back in lower mana tofu / venka mirrors.
Hucker is A tier for me... I think the slow pairs well with Slade / Jicarilla setups and the protect pairs well with EMP armored strike plays.
Fun stuff :)
I'll have to try Thraghun a bit more it sounds like.
As for FFH I like it too, but just haven't placed it as much. Maybe it's because I feel there are other better options when it comes to Void, but the pairing with Craniax is interesting.
As for Forked Tongue yes it's absolutely inching its way to A. And Hucker probably deserves A already - I definitely use it in those Slade/Jica lineups.
Good stuff Mondroid, thanks for the thorough comment!
