The goal is to awaken lands then use them for mana and threats at the same time. After using any of our cheap control spells, such as
Clutch of Currents
,
Rush of Ice
or
Wild Slash
,
Jeskai Ascendancy helps us activate the combo this by untapping any
Rattleclaw Mystic or awakened land (because it's a creature) tapped for mana, as well as boosting them, looting for more spells to repeat the process and filling up our graveyard for our
Dig Through Time.
In an ideal case, with the ascendancy on board, you could continously tap mana dorks and awakened land, playing spells for free for as long as you have the cards in hand. Noyan Dar, Roil Shaper serves as another easy way to awaken lands and create threats.
The best hand would be to play:
Turn1: Green source
Turn 2: 2nd Land + Rattleclaw Mystic
Turn 3: 3rd Land + Jeskai Ascendancy
Turn 4: 4th Land +
Clutch of Currents
/
Rush of Ice
awakening a land for 5 mana, Untapping Rattleclaw Mystic and looting for any other 1 mana spell, such as
Wild Slash
/
Clutch of Currents
/
Rush of Ice
, untapping the Rattleclaw Mystic and the awakened land which is now a creature, leaving 2 mana open to play any 2 mana spell like Roast/
Reality Shift
/Valorous Stance, depending on the awakened land type (a
Mystic Monastery
gives you the most options). Jeskai Ascendancy keeps you looting for any other spell to keep your combo going, or to find a Dig Through Time with your now full graveyard, while boosting the hell out of your haste land for decent damage.
Turn 5: 5th Land + Dig Through Time/Anticipate is ideal for refurnishing your hand with cheap spells to repeat the process.
