Ramp decks didnt perform particularly well at #SCGCIN last weekend, but I also believe that was because people hadnt found the best builds yet and Ramp decks will be a large part of the metagame post-Pro Tour
Spiders tend to be mono-green cards and usually have reach, although the scope of spider creatures has expanded significantly with the release of Marvel's Spider-Man
So, a commander like Noyan Dar, Roil Shaper will have a lot of elementals by their side, although blue and white dont help a lot since you lose on green and red (Creeping Trailblazer, Smokebraider, and more)
I expect to see more cards that scale for multiplayer in the future
In the incredibly rare case where there is no legal target for the first or second mode, those modes can't be chosen at random
You can target 1 face-up monster in the Extra Monster Zone
