Currently you can get a decent amount in sealstone due to your level. However, eventually as you reach higher levels (inevitable unless you're never going to spend a single point of health), your opponents get stronger and stronger, and may in the end have a full five set of strong cards, whereas you, with only four cards, will do poorly. Well, basic math. With four cards you're at 4/5 of your maximum ability, whereas (I assume) everyone else won't handicap themselves.

Of course levelling them is also important, so hopefully you'll get more mags to level them instead of choosing between keeping and levelling. A good place to farm is in chapter 2, part 2 (The Souls of Objects), in Kita Sando: Investigation. If you insist on levelling them first, perhaps keep five and level the first two or three first, then slowly level the rest? The next Conquest won't happen until after Tower, which will run another two weeks after sealstone at least. Five cards are important for Tower. You could build it up to ten after Tower. Also, do keep in mind the chance of the skill level going up when you level one using the same card(Wind weasel leveled by wind weasel).

Also, you mentioned that you were choosing cards to keep.

Basically, for an event like tower(which is likely to be the next event), you want to keep cards with skills that say 'reduce the def of xx cards'. You will also need more health here. For an event like sealstone and maybe soulgem(this one), skill cards are that raise the entire team are good(increase divina attack versus increase the daemon's attack). Or if you hunt bots, just keep a team of five wind weasels and go seeking out those 15 def bots.

For an events like Conquest(Werewolf and Magician), you would want to keep cards with high attack and defence(low spirit cost is nice too when you can get it). This is because skills are useless in Conquest, but the ratio of spirit cost versus attack+def is more important then, since you need enough attack and def spirit to send out your teams. The amount of cards you can send out depends on both it and your spirit cost (For instance, if your attack and def are both at fifteen, the total spirit cost of the cards you can send out is 30, and if it exceeds that, the game won't let you send out any more cards even if you do have them).

Hope this helps you:) If not, maybe you could ask a specific question that I could answer?
