This decks combines Muster creatures with Spellcraft effects as single card triggers.
Snowstorm Druid provides Aegis, is a cheap blocker early on if necessary and can stun.
Wanderlust Qirin is a cheap early flyer that can decelerate early on aggression.
Sodi the Metamorph draws cards and enables playing a Muster trigger and a creature in the same round with the power refresh. The power 3 time + 3 primal casting requirements are high, but there are enough dual power and power fixers to reliably cast it.
Swaying Sea Qirin is churning 1/1 blockers to throw in front of large enemy units until I find a stun effect.
Tidecaller casts a one round 4/4. Having it on the table brings the opponent into the defensive.
Yeti Traditionalist is one of the key units to push aggression. Grows to 7/7 with Overwhelm after 2 Musters triggered.
Greenstretch Empath let you draw 2 cards on a Muster - sure way to trigger a Muster every round.
Vinepetal Creeper becomes 8/8 on a Muster and is still available as a blocker due to Endurance.
Majestic Mandrake gets 5 life per Muster. Often I get hammered below 10 before I stabilize and he can bring life back up.
Triggering Muster should never be done with two cards (Spell + Attachment). There are a few cool low costs triggers not relying on Spellcraft:
Elysian Blueprints,
Cobra Gear, and the absolutely great
Storm Hex.
Apart from this I included 11 more costly to cast Spellcraft cards:
Changeestik,
Pokpok's Slingshot,
Sandglass Parma,
Sodi's Spellshaper,
Waystone Fragment,
Grodov's Burden and notably
Tome of Repetition allowing to double spellcast if enough power potentially double triggering Muster.
1
Talir's Favored and 2
Volunteer Corps were added to stabilize the power curve and to cast
Sodi the Metamorph more reliably.
This deck does well in Gauntlet. To make it playable in Throne I would have to trade some spellcast attachments for threat removal cards.
I'm still looking for cheap 1 or 2 power trigger effects. Often I find myself at choice of either bringing out a Muster creature or trigger a Muster effect. It would be desirable to cast a 3 power unit in round 4 and trigger a Muster.
I should probably add
Horde Plunderer and consider
The Throne Room.
Many of the cards are substitutes, e.g. Vinepetal Keeper and Yeti Traditionalist take the same role. Also, most of the Muster effects are mediocre. The diversity helps in having the right effect when you need it. It sort of works while adding more variance into the play.
I like the Wump & Mizo + permafrost idea. Wump & Mizo allow to lean heavier into relics such as Pitfall Trap, Thicket Trap or even Tomb of the Azuremage.
Let me know when you upload such a deck. I'd be curious.
Consider market access and put your 1 ofs there namely burden and waystone, in addition to boardwipe, hard removal, and maybe a cheap muster trigger.
Also consider wump & mizo main deck, he plays snow ball every turn, makes muster extremely easy + 4 permafrosts are a must in this deck
Ps there is also an inscribe relic that deals 1 dmg to enemy board and shuts down armor so worth considering
