The Bellerophon is a tough sell at such a high cost, but the overall value is pretty great. For 7 ER, I want to deal about 14 damage. If you only use this when there is a minion out, over 3 uses you get 18 total damage - great. This increases in value if you hit more minions or get to discard tough statuses. Each use also has the upside of being an Action, not an attack. This lets you use it even if you are stunned, ignores retaliate, and even lets you use it in Alter-Ego form. The downside is the tempo. This will likely use up your whole turn to play and doesn't kill 4+ hp minions in one use. Especially if you have to wait for minions to come out, you could have a massive delay to see your big investment pay off.

The Bellerophon is unique enough that I expect to play it in a few decks, but I wouldn't call it a staple. Against certain matchups, it may win the game by itself, so I will be on the lookout for places to sideboard this in. Maria Hill can justify any of the big helicarriers, so it will always be great with her.

Edit: Stretch22 has corrected me. The attached player gains control of it. I thought because it didn't say "play under the control of" that you retained control. Only the first few reasons actually work. :(

What is Energy Shield? Some quick basics:

-Zero cost to play!

-It remains under your control even if played to another hero. It's your resources spent, not theirs.

-And crucially it's not a hero interrupt. We'll get to that below.

So, depending on your style of Protection, here's how you might use it.

One: A way to ensure you trigger your "when no damage is dealt" cards.

This is very flexible! Off by one damage because someone drew the rare 4 boost? Not a problem anymore! Toss a spare card or tap your Quincarrier to save your economy. Energy Barrier kinda fulfills that too, but it runs out and Energy Shield does not! This is a solid, but not unique use.

Two: blocking non-attack damage.

Energy Shield isn't just for attacks, it blocks anything! Rare issue, though. Handy when it does come up.

Three: when the crap has hit the fan.

Did your Star-Lord pull too many encounter cards again? Did you have bad luck and surge into two or three attacks? Out of re-readies? If all else fails and people are going to die, burning your resources to stave off a almost-loss is pretty good. Again, Energy Shield never goes away.

Four: Wait, it's not a hero interrupt?

Here is the big deal. You can use this card... in alter ego. Had to go heal this round? You can still protect your besties! Want to stay in Alter Ego even longer? Sure, you all stay heroing while I block all the attacks from behind the scenes! Nothing else does this, and it's a really unique effect!

Is any of this worth just how expensive it is to block? One energy resource for one damage is really expensive, and restrictive. Probably niche for most people, but looking forward to seeing someone bust this open!

Can it be Played with Uncanny X-Men(https://marvelcdb.com/card/36018) or Uncanny X-Force (https://marvelcdb.com/card/40022)? because Team Training doesnt have the "Team" trait the other cards refer to.... i know it might be a stupid question because "Team" is in the name ... but i cant seem to find informations about this.

Scarlet Spider's "fail case" is using its basic abilities. 2 thwart and a chump block for 4 ER is not great.

Where Ben shines is sucking up the consequential damage from your Web-Warrior allies, and providing them with extra uses over several turns. Extra uses of Spider-Man/Peter Parker, and extra blocks from Spider-UK/Billy Braddock are particularly valuable, but don't overlook extra uses of Spider-Byte's and Madame Web's Thwart of 2,

I was pretty low on this card, but it sure was devastating to the Thunderbolts scenario 4 of the Agents of Shield box. It's also pretty solid as a stun in a protection deck that wants to run the Power of Protection, but that'll depend strongly on your deck.

Normally I wouldn't be interested in the minion-stunning option, but now that we're seeing larger minion mechanics with the Thunderbolts modules, it's a decent backup plan.
