Man, I would suggest:

Archetype of Endurance, Asceticism and Privileged Position for protection

Doubling Cube, Mana Reflection and Vorinclex, Voice of Hunger in addition to Mirari's Wake to make loads of mana

Primal Vigor as a replacement for Doubling Season, since is cheaper money wise

Nylea, God of the Hunt and other trample enablers

Strionic Resonator, because is dumb with the Chorus

I use all of them in my Chorus deck, all to great effect. Anyway, +1 for a great deck

Hysteria023 Thanks for the suggestions!

Vorinclex, Voice of Hunger is banned at my gamestore or I'd definitely run it. I suppose I should've said that in the description, my bad. Archetype of Endurance is a good suggestion, thanks! As for Primal Vigor, I'm not a fan of it because it also gives the benefits to your opponents. I did not know that Strionic Resonator existed... that could be absolutely hilarious.

I'll consider the other cards you suggested. Thank you again!

Not trying to say anything bad against your playgroup, but compared to the power of Iona and Vorinclex, Reliquary Tower just seems like a super petty ban.

canterlotguardian haha; I totally agree :P Cards there don't really get banned unless they're completely overpowered or someone did something to get it banned, so someone probably did some massive stupid crap that just got it banned. I myself haven't been up there recently so I can't say for sure, oh well, gotta live with it.
