Alright. But do keep in mind, Burning Inquiry does discard at random... so it can hit combo cards for opponents, or lands which they might need.

Isn't ponder banned in modern? I understand its casual but I don't know anyone whose that casual.

Yeah, Ponder is banned in modern, so you'll need a new card for that. Visions of Beyond is a bit pricey (relatively), but could be good. Otherwise, Whispers of the Muse and Reach Through Mists are just basic draw engines.

Simian Spirit Guide isn't too pricey and can help you get more mana more easily. Reforge the Soul is a good way to refill your hand while you are combo-ing off. Sulfur Falls is a cheap(er) dual land alternative, if you're looking for one.

+1 for Budget Modern
