Cool deck concept!

1. Probably, yeah. But I can't say for sure without seeing your entire decklist.
2. Hard to say, depends on your table. Do you think you need something early? A lot of the times people will just ignore you if you have no board presence early.
3. No. Unlimited hand size is usually a bait. Just discard at end step and keep the best 7!
4. Maybe. Depends on how fast the other decks at your table are. If you begin building your board after the first boardwipe (turn 5~) you're in a really good spot.
5. With some blinks, that's probably enough yeah.
