I think we don't need all this, maybe just a bunch of like 10 new cards, so we can try new stuff, maybe a level 6 AI, called "TITANS", with 250 HP, they can play shards, miracles, rares, double draw, so you have a chance to win some rares or shards from spins.
The arena was a great add, coz is a different game concept, you can win electrum with any Idea and play really difficult opponents.
The oracle is great as well, you can get weapons and rares from it.
Maybe another concept will be nice, kind of like "Risk(the game)" but will ETG creatures and stuff.
Or maybe just a simple RPG, where you can use your own avatar, and walk around a town and see other players, and fight with them.
Or a Tower defense game with ETG concept and summon your own creatures to fight.
Is just some Ideas.
Cheeeerrrssss.
