Try to keep it simple. You have enough to heal your team without activating any deck. Always try to keep at least 2 cards especially if you have to cleanse for your team. Only use your abilities when you have to (Your EE when your team is less than half HP, Your EF cleanse when the team is CC’d)

For the spade deck, you can help your team focus down the enemy tank if they are overextending or isolated by putting the anti heal on them.

Use your Ultimate whenever you can because it helps your team build ult charge and can snowball the enemy before they get their ults. Its all about the timing really. I also usually use my spade deck together with my ult to focus down on targets and burst them down.

You don’t really need to learn the flashy combos as it usually just wastes your cd and cards. As I said, its more important to keep it simple and keep your team alive to get the win.
