I think the most OP decks right now, should be Nature using high armor creatures + a lot buffs in stats and there's a strange deck that uses lots of Sleep and board control to stall the game till the late game. But they use many good cards from the new set, and a lot of them are kind of expensive. This mage I built is a pretty simple deck and you can reach the top ranks with it, so I'd say it's pretty good and I always love to play Mage so it was inevitable.
Always great to have you, dude!
Even if I'm having trouble following you up on GU tactics, I'm really happy that you're getting in depth in this game!
It's a pleasure reading your contents and interacting with you :D
Haha, thanks man. I'll be doing some more Splinterlands content soon. Hopefully some very Meta discussions.
