Hermetic Study/Psionic Gift ( Saga/Legacy/Destiny & Odyssey/Torment/Judgment ) In both sets, these cards served a similar purpose: kill small creatures or allow your smaller creatures to threaten large ones in combat (for instance, Hermetic Study would allow your 2/2 creature to attack into a 3/3 creature with the threat of your third Hermetic Studied creature sweeping away the 3/3 should it block)
As an aside, take a look at that art
It seems like similar logic should apply to the G/B Winding Constrictor decks, but in practice the matchup plays out very different from the G/R one
The turn after we play Archangel, we gain one trigger from Nyx-Fleece Ram and can gain one trigger from Courser of Kruphix
Arena looks better, but it currently seems even less capable of doing these things, which means that the program might never have Modern or Legacy functionality
Meanwhile, on my end, connecting to the network in general was finicky, and putting down the iPad for a minute to grab a snack or answer a text timed me out on multiple occasions
