As a grinder, all I want is to figure out the best builds with powerful cards
Heralds Horn is a fantastic reprint as it was starting to get expensive, and pretty much every tribal deck wants one
Load up on cards like Dreamtail Heron, Migratory Greathorn, Archipelagore, Gemrazer and Auspicious Starrix and things will get ridiculous
The amount of mana it can tap for in Enchantress is disgusting, allowing for huge turns, and it can even make infinite mana pretty easy with other enchantments like Pemmin's Aura
If G/R Goggles becomes a large part of the metagame, which I do not expect to happen, then my version of G/B Delirium Aggro is not what you want to play
I should also point out that we did an uncommon creature cycle where you can reveal a creature card or pay extra mana, except this version uses behold to allow you to get the discount if you have the proper creature type on the battlefield
