Here is input from a Type 1 casual/multiplayer. I do not compete in Type 1 tourneys but I've been getting a pretty good feel for the speed of the environment (cough, fast, cough) based on your primers and various analyses.
Vindicate: I love this card in my casual games, but I would be afraid to bother with a sorcery (no matter how cheap) in a T1 tourney. Basically I wait to see if he/she can kill me on their turn (disregard any FoW's) and hopefully they don't I get to go again so I can waste 50-75% of my mana to take out a permanent. I'd rather play Temporal Spring to steal some of their tempo, plus the colors are easier (well green maybe isn't as easy as one would think).
Personally, I also think there is potential for Guided Passage and Ice Cave (Yes I know enchantments were covered already, but what the hell).
Guided Passage reminds me of Demonic Consultation in that its difficult to use properly, but too powerful a tutor to ignore. Still, its essentially 3 for 1, and having 2 extra cards in your hand is almost always good. Maybe its not Type 1 stuff, but someone will build a dangerous combo deck with this card in some format.
Ice Cave I see as the sleeper of Apocalypse. This thing can go right into Turboland in Extended (hello Obliterate/ Exploration beats). No matter when its played, it forces your opponent to change his/her normal game strategy. Bottomline: its a perpetual counterspell every turn given certain controllable conditions.
Fire/Ice: the tap permanent ability is better than people give it credit for. Tapping that permanent will basically get you that one more turn to survive (in most games) while allowing for 2 chances to topdeck an answer.
Evasive Action: I'm not positive of the ruling of this card but Dual Lands kick ass with this thing. Tundra and Badlands would allow for a 4 point Mana Leak. I mean, how often does someone have 3-5 mana open before turn 7?
I'm very curious to hear your response just because maybe you saw something about these cards I didn't, or why they just couldn't work in Type 1. Either way, I can't disagree with any of your other comments regarding Apocalypse in T1, nice job.
