Today I will be in a tournament and had a couple of questions can my team consist of all red elite cards ?

As well my command deck must be 15 cards correct? Reading the rule book(Skirmish) states you must have 15 but can cost 15 or less?

Yes to all.

BUT, each non unique elite is limited to two copies. This includes upgrades like Cross Training.

Awesome, thank you for answering my question

Also say you have the skirmish upgrade indentured jester how would my opponent score the upgrade when the character he is attached dies or they don't get anything because he it a zero cost?

This is a pretty common point for confusion: you're restricted to 1 unique (cards with a dot), 2 elite (red cards, no dot), 4 regular (grey cards, no dot) of the same name

Meaning you could take 2x eStorm (18) + 3x rStorm (18) for 36/40 pts and have 5 deployment cards with 15 stormtroopers running around

or 2x eRoyal Guard (24) + 2 eProbe (10) + ...

The same rule applies for skirmish upgrades: Cross Training is red no dot so you can have 2 copies, Targeting computer limit 4, Zillo limit 1, Last Resort limit 4...etc

Command card is exactly 15 cards, but <= 15 'command cost/points'

For Jester, notice it's an attachment to another figure so you'd score the 1pt after you kill the host (ex. if you attach it to Jabba then you'd score 7pt not 6 when killing Jabba). Same rules apply for other attachments too (ex. attach Target Com to eJet your opponent would get 4+4+1 after wiping out both eJet)

Skirmish Upgrade Attachments are scored at the same time you score the last figure of the deployment card it is attached to.

In skirmish you are limited to up to one of each ▪ unique (whether elite or regular), up to two of each elite, and up to 4 of each regular deployment card.

And you're also limited to one upgrade attachment per deployment card...

thanks everyone been much help on this matter

Also something to remember with companions;

When the "host" unit is defeated, you don't pull the companion token off the board. It remains in play but cannot activate. So if you attached Salacious to Jabba and Jabba is defeated, Salacious would stay on the board but would be effectively useless because it can no longer activate.
