So I've gone through most of my collection and had a few thoughts:
One funky option is to leverage cards like
Irenicus's Vile Duplication and
Spark Double to make copies of Ivy without legendary (or I guess
Sakashima of a Thousand Faces to keep it but not care, which gets things going faster), and then keep doubling the number of ivys with targeted clone effects like
Quasiduplicate and
Fated Infatuation.
There's a sort of "army of two" idea I like, which I think wants either an evasive 1-drop or a very high-value 3-drop (i.e.
Cold-Eyed Selkie) and then loading them up with auras and such. Obviously hitting the ground running is important, hence the 1-drop focus.
A few keywords that go really nicely here - heroic, magecraft, constellation. Depending on which focus, those could be triggering on every targeted spell. That's in addition to stuff like mutate and bestow being good as triggers themselves.
Is this the deck that finally breaks the powerhouse that is
Triton Cavalry? Just keep cycling
One with Nature and
Curiosity until you've got 10 of each on Ivy lol. I don't think I've found such a compelling use for a forgotten trash limited uncommon since [[
Sage of Hours is objectively very strong here. Unfortunately.
Between magecraft vs constellation, I think magecraft looks a bit weak. A lot of the options are either too expensive or don't do enough. Standouts are
Quandrix Apprentice,
Archmage Emeritus, and
Dragonsguard Elite. Lot of mediocrity in constellation but it's a bit deeper -
Eidolon of Blossoms,
Nessian Wanderer,
Eutropia the Twice-Favored,
Setessan Champion stand out to me, with
Protean Thaumaturge being potentially interesting (though it doesn't get much value from double-triggering).
