Can i use "I CAN HELP RIGHT NOW" first in the beginning of the turn and then use "Call IN THE RESERVISTS" afterwards but still in the beginning of the turn to refill the active slot I just used for "I CAN HELP RIGHT NOW"?

Yes, was just discussing that here:

If I am on click like 22 and use call for help, then roll a d6 and hit click 25, can I then use the #3 ability? Also can the called in character also b given a power action to summon a character using the 3 ability?

This is a very good resource. More problematic/tricky if you are relying on the Parachute slots to replace used ID Cards (similar to the Utility Belt). The best approach may be to discard ID cards via Call in Help for characters whose Inspiration effects are more useful than their actual dials.

However, given that this allows for the use of an Inspiration effect at any time (random) AND activating Call in Help on Special #3 without the restriction of point cost, it can be very powerful. The equivalent would be the Infinity Gauntlet: Get to Special #3 ("Godhood") ASAP.

So when you use the call in help ability does the character using the call in help ability have to be higher point value then the character being called in?

Read any ID card for an explanation

If I'm playing Golden Age, can I use non-Avenger ID cards on the Roundtable, like X-Men student IDs or wanted posters?

I think it’s only things that are ID cards. So wanted posters might not work but Xmen faculty and students I’d are good

Wanted Posters specifically state that they count as ID cards. Student ID cards are also ID cards.
