I like these ideas, some Legacy decks for example run a split of {Daze Force} or {Daze Pierce Force} or {Daze Pierce Flusterstorm Force}. Free counterspells are one of the things that make Legacy sweet, but in the absence of those 1-mana counters are pretty wonderful, and Red gets them post-board.
I also like how Spell Pierce can be played around, but if you play around it, it's already kinda done its job. Conversely, I once tried to play around
Spell Snare, but then I got infuriated that my troglo opponent wouldn't tap out on turn 5 or whatever so I jammed the
Squadron Hawk anyway and had the self-loathing satisfaction of confirming my read.
My initiative for a higher concentration of counters is based, I realize now, on Wadds' last point. It's not so much I want to make "UW flash" in Cube, so much that I think such a thing is impossible, as impossible as RUG Delver, and am interested how far I can push things towards there without running the risk of bad design.
