I've played a deck like this though it was all red. I found that the Kaldra equipement takes a long time to get running. I also found that you need about 14-16 creatures so you can draw them and start equiping. The other thing I see wrong is the pentad prism won't acomplish as much as you want since the deck is only two colors and you already have the bauble and ingot.
First off a list of your deck list would help. With the list we could see what your deck is focused on doing and how it make it better against mono blue.
I voted five because it can be any type of permentant beyond a artifact or land. Plus it's superb. I liked the tree as well because it can lead to new abilities for it is protecting a small plant from blue fire.
No it wouldn't work because the damage must be dealt and that means resolved which would have the tender be dead. Though the Jitte will still get counters.
Example: Human Wizard, Bird Wizard, Elf Wizard
Then again that's ONs all over again.

Choose any number of target creatures and remove them from the game. At end of turn return them to play under their owners control.
I think it could help WW and it would be good to use after end of turn followed by geddon on your turn.
Though it's sad to say, I too could not hold in a laugh at that.
*laughs like a crazy loon and runs off*
2) No. Toshi states your graveyard.
Anyone else care to answer?
Player A: I restart the game and remove Hikari.
Player B: Grumble grumble
Player A: I smack you with my beating stick now.
