Quote from Lectrys »Holy moly, will you look at Splicer's Skill! It's got Splice onto instant or sorcery for , and it makes a 3/3 colourless Golem artifact creature token. On its own, it's a sorcery that costs . UWx Control tends to be a spellslinger nowadays, so Splicer's Skill might fit there as long as you like expensive cantrips, removal, and counterspells. It also makes late-game targeted discard better if you feel like this in Junk Midrange. Yes, the token is produced after the Terminus this is spliced to tucks all creatures. And yes, this is nuts Spliced onto Storm and Replicate spells before they copy themselves.
I misread the card initially; I thought it was spice onto Arcane. Splice onto instant/sorcery is amaaaazzingggg. Being a sorcery itself is weird, but splicing onto an instant at instant speed is bonkers good for repeatable blockers/threats.
