My favorite kinds of decks are big mana decks. Not big like infinite mana, or Rampant Growth. Somewhere in the middle, with Cloudpost or Urza lands. As a consequence of this, one of my favorite formats is Pauper, where I played a ton of Blue-Red Cloudpost before that got banned, and currently play all the Urzatron variants. One of my favorite variants looks a lot like this build from ChickenDudePwnz:

Buy This Deck

This shell should look reasonably familiar to Modern players. Tron lands, Expedition Map, Ancient Stirrings, and Chromatic Baubles all help you cantrip your way into Tron as early as turn three with a pretty good degree of consistency. Prophetic Prism stands in as another Pauper legal cantrip that provides a long-term source of colored mana. This is important in this format, as most of your haymakers and interaction are actually colored spells, since there are far fewer colorless options.

As far as haymakers go, everyone loves a Mulldrifter. This is the card that buys you time against aggressive decks while helping you set up a devastating turn to swing the game around. This is one of the most frequent targets for Pulse of Murasa, as you’re almost always looking to keep churning through your deck while stalling the ground or chipping in for damage in the air. The other key threat here is Fangren Marauder, which teams up with all of your baubles to provide an obscene amount of lifegain, which can easily buy you enough time to stick another threat if the first one gets answers, or just end a game on the spot if you can gain enough life at once.

The power of this shell is that you have enough fixing to reasonably run cards of every color. You can splash Rolling Thunder with relative ease. Chainer's Edict or Duress become reasonable cards depending on how the metagame shifts. Various Circles of Protection and Ray of Revelation effects are all completely reasonable splashes. When you’ve got the likes of Prophetic Prism, Prismatic Lens, and Shimmering Grotto enabling you, any splash is possible.

Finally, I love this deck because of how customizable it is. You can play Journey to Nowhere and Ruin Processor depending on the metagame. You can add Tilling Treefolk to rebuy Haunted Fengraf. You can even go deeper and play one Gurmag Angler to control your hits off of Haunted Fengraf. It formats are particularly heavy on edict effects, you can play Maul Splicer as one of your threats. The possibilities are endless, and if you tweak to keep up with the metagame, your deck is never exactly the same twice.
