Goro-Goro, Disciple of Ryusei Goro-Goro, Disciple of Ryusei is a bomb way to take advantage of your creatures with modifications: That is, equipment, auras, or counters
If you'd rather opt for something a little sneakier (Sapphire Dragons are all about military tactics, so they'd no doubt approve), you can call upon the Adventure ability and use a Psionic Pulse that counters target noncreature spells
Personally, I had a soft spot for Core Sets, so hopefully Foundations will fare better than they did
The serialized Headliner of the set is The Aetherspark, which is also pretty desirable in its other prints
Because Magic the Gathering was the first trading card game, there weren't many guidelines to follow while creating the original sets
