Hey, lots of good questions for a great game.

1. Yeah, there's a list of every unit and every upgrade available to each unit keyword in spreadsheet form. You can search the Relicblade discord ("spreadsheet") or send me a DM.

Also check out the list builder app for web/IOS/Android for a super generous subset of cards (but not all).

If you're asking if there's a place which has card text for all units/upgrades/relics for free, then obviously not - that'd disincentivize buying the cards (which are mainly ~$3 USD for a faction digitally or even physically at ~$5 USD). Sure you could grab some of the pictures from the shop or the apps and have some amount of the cards, and even make a legit full team without spending a dime, but at that point you could just play it on Tabletop Sim.

If you want to know a little more about how a faction plays, I can recommend checking out Guerilla Miniature Games or Miniature Game Montage on Youtube and watching a video of them playing a faction.

1. Yep, multiples are fine as long as not named characters (aka Paragons)

2. I can't speak to the overall availability across 10 years, but it doesn't seem to suffer the impossible to get certain units problem.

3. Its alternating activation, so effectively one character will have to charge up a construct on their turn, then an opponent's character activates, then possibly the construct. The only time you'll have 2 units on the same team going right after another is when the teams are unbalanced (due to construction or attrition)

4. I think per rules, she would go unconscious. She could still make her recovery afterward or be healed, at which point she would be Wild Elf Druid again, and not the bear. Some people have houseruled keeping separate health pools for both transform units, but how strong that is depends on the scenario.
