Im not sure Reflector Mage has a home in Standard right now, but it nearly made it onto the Top 10 for this set based on power level alone
Spring-Leaf Avenger will be at home in decks as diverse as Otrimi, the Ever-Playful (who will no doubt get a shout out again today) or even Yarok, the Desecrated, where itll bounce other creatures to be replayed
