Sunspine Lynx comes down as a 5/4 body and immediately burns them for each nonbasic land they control (they run Spirebluff Canal, Riverpyre Verge, Steam Vents, plus Multiversal Passage and Starting Town), while shutting off any incidental lifegain. Magebane Lizard punishes their dense cantrip/burn suite, since every noncreature spell they cast deals damage to them equal to the number of noncreature spells they've cast that turn. Stingcaster Mage and Tomik come out since this is a race where their Slickshot Show-Off and prowess creatures like Elusive Otter grow fast, and we'd rather have bigger bodies and direct damage than small value triggers. Keep Burst Lightning and Plasma Bolt to answer their low-toughness creatures before they snowball.
