I'm building a Grim Patron deck right now. - http://www.icy-veins.com...-one-turn-kill-brm-deck
When i finish it, will HR support this deck and its play style?
I asked that question because I think it is not smart enough to run the combo.
If so, i'll need to use deck rule (Which deck rule?) or can Silverfish do it?

Dont think is even posible atm, AI arent intelligent to do those "keep on hand till combo" and combo enemy. Maybe with a custom rule it can be "near" to a patron deck but there is still a problem and is that one Cloud said, theres not enought time for calculations and moves.

Silverfish can do custom combos but when I tried to have it do grim patron it failed horribly. Even with all options increased for max speed, the bot is way to slow to handle all the animations and board recalculations. Even many top pros have trouble attacking with everything in 1 turn. I remember a match in a tourney with patron warrior vs patron warrior where 1 guy missed lethal because he ran out of time and then the other guy got a mega frothing off all the patrons on board.
