I just answering about the deck processing below, cause it's too long to explain all here, sorry...
* About Becon Bolt, you can remove a
Radical Idea (only one) because you got 4
Opt normaly, unless you can remove
Maximize Velocity, but you lost a fast
reaction if you need Haste during a turn, that depend the deck you facing...
It's normal if Gruul got difficulties against Esper, cause Gruul got few answers, but overuse of Creature abilities to facing Blue (Like
Sunder Shaman) hard to manage...
Thanks a lot for your questions...
