Has anyone tried splashing red? I recently changed my deck from white/blue to white/red for simian spirit guide and tunnel ignus. The best draws would play an annoying 2 drop turn 1 then play out the remainder of the game as normal (minus blade splicer flickering). Ignus works as a pseudo arbiter 5-8, while not disrupting nearly as much it may cause your opponents to use fetch lands at times when they wouldn't want to. Also once you get to a mid game, you can use flickerwhisp off aether vial to deal 3 if needed.
The current list looks like:
4 Aether Vial
1 Sword of Light and Shadow
3 Thalia, Guardian of Thraben
3 Serra Avenger
4 Tunnel Ignus
4 Leonin Arbiter
1 Magus of the Moon
2 Aven Mindcensor
2 Brimaz, King of Oreskos
3 Flickerwisp
4 Simian Spirit Guide
2 Hero of Bladehold
4 Path to Exile

I have only been able to play vs. robots and grixis control which isn't enough to get a feel for the value of the red cards.
