A 14 Printed Attack?!!

Yup. A printed 14 attack. He's nasty.

I just played him with Barbatos , and captain venom. Barbatos gives monsters batman enemy TA so go ahead and share that 14 attack value. Bonus if captain venom attacks first then monsters get +1 attack. My 10 attack just went to a 15.

I guess the rule of 3 does not apply anymore? Here I thought combat values can only be increased/decreased by 3 unless stated other wise?
10 attack to 15 seems to break that rule.. but I've been outta this game for years so rules could have changed I guess

If he uses the Batman Enemy TA granted by Barbatos it would replace his attack value, not modify it.
And after the replacement his attack value could be modified further.

I love the nod back to the Infinity Challenge Nightmare with that attack value

I love It! I got this after my first sealed tournament. But i can't understand if this (with the other limited like baron mordo) can be used in modern age tournaments. Anybody knows?

Yes he's still modern legal
