Without further addo, into the decks mechanics and idea. This deck aims for a OTK with a kicked
Fight with Fire, thats been copyed by
Primal Wellspring or doubledamage buffed by
Insult. May not be outright effitient, but cool as hell when things happen accordingly. In order to make that possible, time is needed and that's exactly the role of control, while ramping fasten up the process.
Stalling
All removal comes in with the effects of buying time for the combo to come in. Gleaming Barrier blocks small ground creatures, whilest generating treasure to help ramp up needed spells and it survives Sweltering Suns.
While beeing the win con of the deck, Fight with Fire itself helps keeping your lifetotal until the big fireworks show up.
Primal Amulet
is another piece of the puzzle, that easen up mana cost until fliped for straightout value. Insult has good sinnergy in this case, putting up 2 counters while beein 2 mana cheaper overall, helping to control and possibly (but kinda unrealisticly) doubling damage for the combo.
Other removal need no especial explanation.
Ramping
Jaya Ballard, Treasure Map
and Pirate's Pillage all serve as a means to ramp spells, while making it easier to cicle through the deck, with the first also helping as a second win con.
Others
Cards like Abrade or Scavenger Grounds came in for the versatility edge the deck sometimes require. In this especial case, Mirage Mirror was included with intent to bring this versatility up a bit.
