Ok deckbuilders, once again I am excited about
Grand Architect. I am convinced there is a powerful mono blue artifact deck available in standard.
The blue creatures:Enclave CryptologistRiddlesmithTrinket MageGrand ArchitectThe artifact creatures:MemniteMolten-Tail MasticoreWurmcoil EngineCryptologist can quickly begin cycling your hand to draw you into your threats and at the same time fill your graveyard with fodder for your masticores. She only costs 3UUU to turn into a draw engine that will negate the masticore's drawback. She should be safe to level up as your opponents should be spending their removal on your architects and artifact creatures.
Riddlesmith fills a similar role to cryptologist, cycling and filling your yard, but he does it for FREE. He can also be a decent beater with some architect buffs.
Trinket Mage searches for memnites and chalices. These are good cards to discard if you have an active Masticore and the chalices provide an alternate source of ramp if you have no architects.
Masticore can hit play on turn 3 often, either via architect and tapping 2 blue creatures, or by casting chalice for 1 on turn 2. If you untap with him he is very hard to remove. He can swing for 4 (5+ if you turn him blue) and ping for 4 (if you dissed a creature) on turn four. Keep in mind that the 4 damage can be directed at planeswalkers.
The rest:Everflowing ChaliceMana leakStoic RebuttalCounters and ramp.
