Hey dcucco, thanks for your questions! Apologies for the late reply, but here goes:
- Activation on Discard, Draw and Removal effects are planned to be added in Version 1.4.0. It should work exactly as you have outlined.
- As of Version 1.3.5 (current version as of this post), it is now possible to summon party members who have their own deck! You can do this either via Eval or through a Common Event attached to a Skill. Some funkiness does happen when you summon the same party member twice, we should have that smoothed out by Version 1.4.0.
Hope that helps. Let us know if you have any other questions or requests :)
