Some really rad cards, with inventive concepts motivating the design. Love that not all Mechs will be geared towards building Mechazor; makes playing a Mech dech less of a by-the-numbers thang. The Build concept is cool, though I suspect it’ll ratchet up the # of destroy/transform spells we’re all stocking, while making our dispels less valuable. (Though can you dispel a Build once it’s complete? Know you can’t dispel it while it’s mid-Build.)
But dayum, if you compare to other cards w/similar-ish effects/value there are several new offerings that should cost 1-2 mana more than they do!
Steadfast Formation (should cost 3 mana, total), Dauntless Advance (3-4), Sunbound Pavise (3), Surgeforger (4), Bamboozle (4-5), Wildfire Tenketsu (5-6), Progenitor (6), Gigaloth (5-6), Auroraboros (6), Draugar Eyolith (7), Bloodbound Mentor (4), Redsteel Minos (4), S.I.L.V.E.R. (7).
I can break down the “why” for each of these. Curious if others agree.
