What common spell beats it, and what is that technicality
No, just a Narwhal
Look no further than the exceedingly aggressive Toxic Storm Modern deck for evidence of that
Either way, a 3/4 Flying Lifelink for five that can resurrect creatures every time you go to pass the turn is phenomenal
The deck starts by casting a number of powerful creatures with spell synergy including cards that generate token creatures (Talrand, Murmuring Mystic, Third Path, Young Pyromancer, Baral and Kari), ping/direct damage (Guttersnipe, Kessig Flamebreather, Firebrand Archer, Electrostatic Field), card draw (Niv-Mizzet), cost reduction (Kaza, Haighty Djinn), any many more
Corey and I took a hard look at the set, and decided we wanted to up the count of Spider-Heroes and pull in some lesser-known ones
