Skaven: Ambushing Screaming Bell
The horrible-obnoxious idea described in the title came in my brain and I cannot take it out from there.
A Screaming Bell can join a clanrats unit, the clanrat unit can take a warpgrinder, the warpgrinder gives Ambushers special rule, without mentioning infantry units only.
I'm ready to take the risk to have a costly Grey Seer appearing late in the game, just to see the face of my enemy when I bring the 40 clanrats with Screaming Bell and Grey Seer right behind them or on the flanks, ruining all their plans. I would play Hallowed by the name of Iron Maiden as soon as my dice makes a 4+ for the reinforcement.
Please indicate me if there is, purely rules side, a flaw somewhere. (I completely agree this is probably tactically not a good move but it would be funny once)
