Finish the game on 7 days?

I guess the hardest part is the early game, but loreangelicus is right, CW offer many things which ease early game. Well, this is some input from me for reference.

KB CW offer a lv 5 unit that is not a random spawn (rune mage), and you can get this early, warrior and paladin can get this at the end of scarlet, ofc this is if you have grand strategy medal lv 2, which is easily doable.

As warrior or paladin, usually it's just thorn or the new orc tracker, orc shaman is also good (but i prefer tracker), and inquisitor for support (pet dragon spam). Pet dragon kick attack and treasure dig are top priority.

After clearing all enemies in debir except heroes, amelie usually have enough lv to tackle some of the heroes if not most with just that setup (might have to add royal snake), though she must kill them as quickly as possible, or some losses is unavoiable due to flame arrow or poison skull, but grand strategy 2 is top priority. Left some of the heroes which is impossible to kill without loses, because you'll go back to this island later. Just kill to get grand strategy 2 and level, leadership must reach 2k asap

Scarlet is almost the same as debir, pet dragon do half to almost all the work and the mission is same (Just kill to get grand strategy 2 and level, leadership must reach 2k asap), especially if you have trap spell early (as mentioned by impy), yet from my experience, trap in CW is buggy (units that are forced to enter the trap won't lose their turn). By the end of scarlet, paladin and warrior can get rune mage, this unit always spawn in debir (royal university) and scarlet (small island).

Though with high luck you can get call of colosus spell, if you get this spell, try to get red dragon or troll, yet this way is not 100% guaranteed, i mean getting the scroll (not the red dragon after you have the scroll). But rune mage usually suffice, ofc in case of damage, it is not as great as red dragon, but it is there for rage gatherer, tanker, debuffer, and summoner. If you utilize it right, it can come close to red dragon.

After getting rune mage and most of scarlet is cleared, as usual go to bolo. Left most or all of your units (up to you though), and switch to droids. You can still bring the inquisitor for extra rage gatherer and more dmg dealer (rune mage can resurrect them). Most of bolo can be cleared with just this setup (including heroes, and even the rusty anchor map guard, not sure about verona guard though).

In rusty anchor, things become much easier, because there is another lv 5 unit which always spawn, the green dragon. You can left all your army and use only the green dragon or otherwise, up to you. Using full army means your pet dragon will level up faster but more risky to do no loss, though it's up to you, because by this time some people still aim for grand strategy 3 (so no loss is a must), yet some do the otherwise. Again, not all enemy here must be killed, because you'll back to this island later (unless you want to skip that quest). By the time you arrive at verona, things become much more easier, so no specific input there.

It must be noted that losses won't decrease your final score (it just affect your pride when other peoples look at your score and personal satisfaction), unless you use a mod to modify how to calculate the score.

At this point, losses are acceptable unless you still aim for grand strategy 3. Though it must be noted that high amount of losses means less gold, gold is still very important at this point, because a very good artifact which usually cost 20k to 50k or more might spawn early. Another thing is, by this time your units is still few, so even a little losses might have a big impact, not only affect your gold, but also time required to restock them (you need to go to bolo which is a very waste of time, unless you still have some bussines there).

Though as paladin resurrection build (there are 2 major build for paladin), at this point you should have resurection 1 or maybe even 2, with this you can have losses as the resurection skill will resurect them anyway. But it must be noted that it will count as casualties/losses at the score screen, again it must be noted that losses/casualties doesn't affect score (only your pride and personal satisfaction). If you use paladin with resurection, i recommend taking losses, but keep in mind to your losses, calculate it, so all your losses will be resurected completely. Why taking losses? the advantage of taking losses is you can tackle enemies at the time when it is too impossible to tackle if you're going no loss (this is only for paladin with resurection though), the purpose of this? it is obvious, high jump on anything, i mean getting very high amount of gold, level, pet dragon, and aquiring late game island map early.
