Astrologian buff effect

[Bebekurenai]

An alternative would be what I did:

associate the colors of the cards with their normal effect and enhanced/extended Royal Road effect. Group them together in pairs for easy association. Use logic to understand what they would do on their own or enhanced/extended.
- Bole + Balance = green HP bar (therefore defense) + red attack power (like a brutal fire) > both will enhance potency
- Arrow + Spear = picture of an arrow (quick knock, fast raining arrows therefore attack speed) + falling star (a bit hard to associate so I assume its for the "other" speed) > both will extend duration
- Ewer + Spire = blue like mana (normally mana is depictured blue) + yellow like TP bar > both will AoE

It helped me like that. Before I used to write the cards down, but I could never memorize them. I've made the association in pairs and now I can instantly assign all cards correctly.
