I would reccomend Venerated Teacher or Time of Heroes

Redace878 dude those are some great suggestions, much appreciated!

Student of Warfare

I'd put in as many Time of Heroes as you can. Venerated Teacher saves you mana if you have 3 or more mana of level counters out already (he's proliferate on a stick). I'd also add Skyship Plunderer alongside Thrum.

To find space for these, I'd cut Gilder Bairn since it's so much mana to cast and activate. You also have only 58 cards here...so you get 2 free adds! Then I'd consider cutting some copies of your color-intensive 2-drops like Commander and Dragonlord, especially if they're cards you want to cast reliably T2.

This is really cool. +1

How have matches been so far?

Astral Cornucopia is awesome in proliferate. Once you get it out, it starts to really pay off since you can essentially double your mana for each proliferate trigger. Helps you level up stuff very quickly.

landofMordor sorry for the late response, great suggestions, all added!

RUST-O Thanks man, I appreciate it. Unfortunately the deck is quite slow and not really viable against top tier modern decks, but it is quite fun, especially if you like watching your counter dice go up every turn!

Hyperalgialysis seems like a really dope card, but this deck already runs quite slow so it might not be what it needs to be competitive, but screw that, i wanna make huge amounts of mana! ill test it out soon

Just a way that I have seen it used effectively. Turn 1 Student of Warfare turn 2 Thrummingbird turn 3 Astral Cornucopia attack with bird level up student 2x. Turn 4 attack with bird level up student once and then 3 more times after astral has 3 counters. So the turn after it comes down it can tap for the same amount of mana spent to cast it and after that it gets stupid fast.

Hyperalgialysis Interesting, ill have to playtest that and see how consistent it can be.
