Advice on which cards to keep?

Hello! I’m moving to Europe this year (but uuwi pa rin sa Pinas from time to time) and I’d love some thoughts on which of my cards are best to keep. I have 2 inactive cards din under BDO—would it be worth to activate them? Also, lahat ay hindi NAFFL 😭

CURRENT CARDS (highest-lowest CL): - BDO Platinum Visa - RCBC Platinum JCB - Metrobank Titanium Mastercard - BPI Gold Rewards Mastercard - UnionBank Miles+ Visa Signature

INACTIVE (shared CL w/ BDO Visa): - BDO Platinum JCB - BDO Platinum American Express

Rn I’m planning to drop Metrobank cos ang hassle ng payment method 😂 But would love to read your thoughts!
