The tactics are there, man... a summoned Arkadon (easy) will devastate a group of warmachines. If they're not clustered, there's a tactic for that, too.
Given the Bastiladon's abilities, even a non-summoned one can make cake of warmachines.
Again, it does seem pretty well-balanced.
I assume Arkadon = Bastiladon? Sorry, that one's new to me.
Anyway, your tactic is plausible. A Slann, assuming its player got to go first, so it's not slain immediately by cannonfire, and assuming the battlefield was small enough, could indeed summon an Arkadon within range of a cannon and then, assuming it rolled well, destroy it right away. (I'm not sure if you use the Cannon's save or the Crew's save, since the Cannon warscroll expressly makes the crew part of the unit? But if that was true, why would they have different Saves? Also, why would you ever target the Cannon, since they're so much tougher? Can crew move between cannons? The cannon rules talk about "its crew," not "any crew..." Ugh. Topic for another thread
)
Unfortunately, the remaining cannons, with two shots each at full strength, probably still destroy the Slann. The Arkadon probably lives though, which is genuinely interesting, though I'd expect it to die on the next turn.
I suppose after that, nothing stops me from taking five Slann, and summoning five Arkadons. But then, we're back in the arms race.
Anyway, thank you for demonstrating that there are ways I hadn't thought of to protect heroes - aggressive offense, creative summoning, forward-thinking army selection, and so on. That'll give me some things to think about down the line
