Oh sweet lord. I don't know how many times I have to quelch this myth of "SoFI is bad on a Dragon". I have played DS longer than any of you foo's and sword on a Dragon has NEVER cost me a game as compared to Jitte. The closest it ever came was a race against combo, but Jitte would have left me 2 life short of winning. Sure, it takes away double strike, but all you're left with is a ho hum pro bolt/bounce evasive creature that is going to do 7-12 damage, possibly kill a creature, and draw you a card. Woe is me.
As for Trinis main, it really goes to the heart of playing this deck. There are a lot of choices that are both meta dependant (kind of a cop out) and I'm going to call it "risk-reward" dependant. Trini, as well as Arc-Slogger, Seething Song, and equipment all fall in both categories. By cutting them all, you would have an extremely consistent deck that relies on it's disruption to stall. However the deck will be fairly unexplosive. The correct move is to find how many of these elements you want to run (and really a lot of it is personal choice).
