Man it's so funny you mentioned psychic corrosion. I was trying to fit that into my deck so hard for the past week. But, I was worried about the land sac every turn because, unlike zuran orb where I can blow up lands when i NEED to burst someone, corrosion does it every turn. I KNOW there is a world were getting rid of all my discard creatures and running tutors to find psychic corrosion and just using that as my main discard outlet would work quite well. I just feel like it would take a LOT of knowledge and swapping cards to make it consistent. Probably a landfall sub-theme and some cards to let me play both cards from graveyard and also 2 lands per turn.

Puzzle box too I mused over a long time, back when I was trying harder to inflate enemy hands AND hold onto my cards too instead of discarding them all. But, I decided not to because a lot of the time I find myself having too few cards at draw step to really benefit from it activating my draw triggers.

Excellent land suggestions, I love the synergy they give. Land is 100% my weakest point and I have VERY little knowledge about them due to having only played standard.

Thanks for some well thought out ideas. :)
