Hey folks, it's been a while and I'm trying to get back into the game. I can't really afford the full Grixis Delver package for Modern, which seems to be the main Delver deck over there, and I'm playtesting this pile I've come up with. I have the feeling that countermagic in Modern is straight up worse than in Legacy, and in that context the Lava Spikes have been really helpful in getting there late game. Any ideas for improving this list? Thanks in advance!
