For starters, lets make our manabase good, which is a pretty hard thing to do in 93/94
In Simic, I mostly see people shoot for Arixmethes, Slumbering Isle
Arcanis the Omnipotent Arcanis the Omnipotent very famously goes infinite with Mind Over Matter to draw your entire deck, which blue has no shortage of ways to exploit (looking at you, Thassa's Oracle)
Providing a use for excess mana at the end of the turn, Autonomous Assembler can slowly get bigger while consistently punching in with Vigilance
Factor in that blue has a ton of ways to draw cards and manipulate the top of its library, and you have the groundwork for a strong value engine
