One, no you're wrong. It's only one turn they'd be denied.And any reb worth his salt will carry R3-A2 & Flechette Torpedoes in combo to double stress easily in a Phantom heavy environment.
Put that on an 8+ pilot and even Whisper won't recloak with ACD for 2 turns.
Well, stress is removed one at a time. Horton, Luke, whoever with that combo double stresses any phantom before ACD kicks in, preventing it from kicking in for two turns.
Two, you're assuming the Imperial player won't be taking advantage of the new cards as well. Why not throw in a cheap BST with Wingman? I know I intend to. Maybe even two to fly escort for my stress-heavy ships like Fel.
No, I'm not. A ship with Wingman is going to have a very hard time to stay in range 1 of a Phantom.
Three, you're assuming that the rebel player will always know he's about to face a Phantom. There are so many combos in this game even before wave 4, the sheer level of prescience needed to build a squad to beat up mid PS phantoms (your idea mostly falls apart if they've got Veteran Instincts on them) is uncanny, especially in a tournament setting.
Hence my Phantom heavy environment statement. While the ability to double stress is never bad, my post is a suggestion for a local meta where Phantoms are ubiquitous.
This whole thread started out with OMG PHANTOMS ARE WAY BAHROKEN OP!!!! And I've given several counters to Phantoms that show the game is still balanced and that Wave 4 contains most of the balancing factors to Phantoms.
Going by your means of thinking, I could then say "OH YEAH WELL I'LL JUST HAVE MY DEFENDER SHOOT HIS ION CANNON AT YOUR GUY AFTER HE TAKES HIS OWN STRESS TOKEN AND THEN I WOULD KILL HIM DEAD," and suddenly it's devolving into a "my dad can beat up your dad" type scenario.
Which is not something I'd say, people presume too much as it is.
And also, though I hate to bring conjecture into this, we still don't know what Tactician does. It could very well be helpful in this situation. There's already a lot of evidence to suggest it gives tokens, but whether those tokens are stress tokens to another player or focus or evade tokens to itself, it could still be very useful in dealing with a situation being described in the whole "this thing FLAT OUT kills Phantoms" debate.
I highly doubt it gives out evade tokens, it's shipped with the Phantom which already comes with an upgrade to hand out evade actions.
