A lot of the ramp is Creature based - Elf mana dorks like Elvish Mystic and Llanowar Elves
To get to a place in which you can play it, though, youll need cards like Prismite and Prophetic Prism, which allow you to pay mana in order to gain mana of any colour, and Skittering Surveyor, which lets you look through your deck for a land card of your choice and put it in your hand
Having 3 toughness means its not likely to die in combat in the early game, which is great for allowing it to attack and trigger
This deck is led by face commander, Tidus, Yunas Guardian: a three-mana 3/3 that allows you move counters across your creatures, and to draw a card and proliferate (add additional counters) when your counter-enhanced creature deals combat damage to a player
It seems to be showing up in some of the so-called Ruby Storm lists lately (the name coming from the Modern deck)
Pauper Dredge plays a bit like a Reanimator deck at times, running the Exhume/Troll of Khazad-dm package you often see in such lists
