Be a bit wary of world champ cards. They are not real magic cards as far as I can tell (even tore one open to check), the paper and spring is different. I think they are closer to the cheap token cards that wotc includes in packs.
If you are playing for stakes, there is a risk of being called out.
@The-Gremlin-Lord Breiwing up a deck with discard creatures, Gemstone Caverns, Chrome Moxen, Forces, as well as Laylines of Anticipation and 4x Days undoing. Not sure if will work, but seems powerful and worth trying out. Ramp, extended hand, flash spells, and 4x 3/4 Time Walk/Time Twister that refills hand after all that pitching. Maybe adding Notion Thief for extra hijinks.
@The-Gremlin-Lord Interesting. Would Gemstone Caverns, Chrome Mox, and force of will (misdirection) plus misthollow (and maybe a torrent elemental or two) combined with several draw sevens have been better? (Don't think it will work with the Amulet mana base, it floped when goldfishing together).
