Green Is Good (for my budget)

All the credits go to Green Is Good (Updated).

For my budget, I have swapped the following cards:
- Shen-Ra, Unbreakable for Kira Ascending, as I own the "Awakening" campaign,
- Helena, Skyguide for Icaria, Valkyrie Captain, as I own the "Dead Reckoning",
- Tarra, Ever Loyal for Spirit Guide, until I get the "Stormbreak" campaign.

Edit: I have been able to craft Helena, Skyguide. The current swaps are:
- Shen-Ra, Unbreakable for Kira Ascending,
- Tarra, Ever Loyal for Icaria, Valkyrie Captain.
Indeed, Spirit Guide seemed less useful than Icaria, Valkyrie Captain in practice.

Edit²: I have been able to purchase the "Stormbreak" campaign. The current swaps are:
- Shen-Ra, Unbreakable for Icaria, Valkyrie Captain.
Kira Ascending has synergy with the deck, but I find Icaria more useful at low power.
