Bring out artifacts like Gingerbrute and buff them up with Steel Overseer
Ensoul Artifact and Animating Faerie animate non creatures to make some powerful threats, especially if you animate an Darksteel Citadel or Darksteel Ingot. You could have an Indestructible 5/5 Creature by turn 2, ready to go for damage turn 3.
Crystalline Giant gets you all sorts of counters, hexproof being the best of the bunch.
The Ozolith saves your counters and gives them back. You can also make it a creature and keep the counters on it, absorbing the power of its fallen allies.
Some Counter spells Quench, Metallic Rebuke and creatures like Siren Stormtamer to keep your threats on the board and to answer removal or exile
Renowned Weaponsmith gives your artifacts ramp and shuffles your library if needed. (though I don’t know when you’d want to, will need further research)
Mana sinks include Hangarback Walker and Stonecoil Serpent
“MechaGodzilla” becomes a swarm of blockers and threats if it dies. (if it gets exiled, then nothing happens unfortunately)
And who could forget Ornithopter, sure it seems harmless, but if it gets any counters on it, it can get pretty ugly. (Not that ornithopter is ugly, it’s a rather cute artifact)
Fun with Artifacts and Blue!
Any comments would be greatly appreciated
Thanks!
