this deck is pretty simple there is only three cards that aren't basic lands here is how to play it
turn 0 mull till you would have a starting hand of 0 cards, this is to help prevent you from drawing chandra's ignition or country's crusher, plus slightly increase the odds of pulling the combo off.
turn 1 play mountain
turn 2 play mountain
turn 3 play mountain
turn 4 play mountain and Plargg
turn 5 play mountain
the end step before your turn 6 Tap your five mountains and activate Plargg's second ability. the only card it can find is Countryside crusher, Plargg lets you put it into play
upkeep of turn 6 crusher's ability activates, you will mill lands till you uncover chandra's ignition.
draw step, you will now draw chandra's ignition since it is now the top card of your deck.
MAIN PHASE
play chandra's ignition targeting Crusher, hopefully you will have mill enough lands getting to chandra's ignition that you can win via dmg.
turn 6 if you failed to win with chandra's ignition, Crusher still helps you out by milling out the rest of your deck, allowing you to loose and leave the game, without scooping
