Budget deck : Seraphine, Starry-Eyed Songstress

Seraphine, Starry-Eyed Songstress takes 2 energy off a spell if you exhaust her and three friendly units as you play it. Go wide with cheap bodies and tokens, then exhaust them for spells far above your curve.

Mulligans: keep Strigian Oracle or Meticulous Restorationist, Concert Poster and a 3-cost body like Vanguard Captain. Send back anything costing 6 or more. Seraphine, Inspiring waits in your champion zone.

Early game: put Concert Poster on a battlefield you control, pay 1 for a Recruit in your base, again on each conquer there; then Vanguard Captain (Legion) brings two more. Play Seraphine, Inspiring on turn 2 or 3: she draws 1 when three units exhaust together, by a move or the legend, once each turn. Battlefields: Trifarian War Camp for the wide board, Packed Amphitheater for your champions, Rakelstake for a Predict.

Mid game: use the legend on their turn. Your ready units can pay it, still fight while exhausted, and stand up at your Awaken: exhaust the legend and three of them for High Note or For Demacia! at 1, Moonlight Affliction (-10 Might) or Clairvoyance at 5. High Note is -1 Might per exhausted unit you control, often -5 on their turn. Party Crasher costs 1 less per exhausted unit: after a four-unit attack, a 6 Might Tank for 5. Rousing Display shows off a card costing 7 or more for four Recruits.

Late game: while Heimerdinger, Academy Instructor stands at a battlefield, each token you play can be a 3 Might Mech, even in your base. Supernova is not a Reaction: pay the legend on your turn with three units that stay home, 7 energy for 10 damage and 2 cards. A card costing 7 or more replays Meticulous Restorationist from your trash for an Order rune. Rocket Barrage with Repeat hits two units in a base.

Mistakes to avoid: - Paying the legend with units that should attack - High Note before your units are exhausted - Rousing Display with no 7-cost card to show off - Tokens while Heimerdinger sits in your base
