Viable replacement for Level Playing Field? Or rather, some kind of rare enchantment that rewards you with mana acceleration for your Discovery.

Does the use of "your discovery increases" feel weird to you? I guess its a simpler way to write it than it normally would.

I did have some uncertainty about how to word it. There may be a better way to word it.

I think it's a good wording. It's intuitive and straightforward, just weird ruleswise, so as long as it works I think it's good. Card seems weak though, I don't see you getting more than three mana on average with this and with delay and sorcery speed casting and triggering, that's pretty bad. Maybe add draw a card on ETB? May clause seems pretty redundant as well.

Maybe this could be ? I like the simplicity of the card and dont want to add to much else. We could add drawing, and just keep it costed as it is.

I do like that with the draw addition it wouldn't be a dead card in the late game, but I could see moving to instead.

I'd be tempted just to change it to G. I was originally basing the idea off of Lotus Snake, but for Discovery instead of Landfall. But sin ce this is not on a creature and Discovery increasing is technically weaker than Landfall as a trigger, bringing it down to G seems balanced.
