Tactical timing of cards played is everything.
I did a Linza vs Linza today all the way through I was cycling up a weapon with the plan to get off a powerful attack if I could but expecting it to be cannon fodder for the opponent whilst holding back a sgs and a nice set of boost cards.
Meanwhile they played a gold farming game and never once deviated so I knew chapter 5 their plan was to throw down a wep and boost it.
What did I do?
I abandoned ship on my sgs basically.
Threw down a jubbly in slot 1 basically wasting a move and getting some heals, already had an ok wep at 8 attack
They played their sgs with its 2 durability.
Slot 2 they played a mob to get some gold.
I played a dual.
Result? They are at 14 health with no sword - their slot 3 and 4 were both +3 attack damage to wep cards.
My slot 3? The one where you throw x2 wep attack at them for a cost of 3 durability.
My slot 4? I had a +2(3?) durability card as back-up incase we reached final fight so my sword would last.
What this fight showed fights nicely with the topic here at:
My opponent played the "Classic" obvious Linza strat - setup for a final sweep on the expectation early weapons will be lost. They did not deviate from this route at all, even though I hit them and was whittling health down early on.
Meanwhile I assumed they'd play that strat so went for cheap and easy damage early on. When they resolutely kept to the 'chapter 5 big weapon' strat I realised they aren't hassling me - I can build a bigger, better weapon early on, which I did whilst setting up my hand as best I could to purposefully counter their chapter 5. I knew in about chapter 3 I could sweep them easily if in turn 2 of chapter 5 I could make them break the weapon or at least weaken it because they did not adapt their tactics to the situation at hand.
For me the strategy you play should be something that is fluid and continually evolving.
Step 1 is when you pick your hero you establish a core aim of your strategy
Linza - build weapons
Raptor - build armour
Ariane - get a big hand
Ozan - farm gold
Step 2 is when you see who you are fighting you aid a 2nd core aim
Linza - make them break weapons
Raptor - hit them a lot
Ariane - Force them to play cards
Ozan - Stop them earning gold/keep my gold low
Crucially BOTH core aims most inform how you play from now on, not just stick to what core aim 1 dictates and ignore the opponents moves.
Step 3 is when you get your initial hand where you work out a rough strategy
These are the cards I have so the best thing I can do is X
But If I hold onto these I might be able to do Y
Step 4 a,b,c and d is adapting after each Chapter.
At the end of each chapter you evaluate what play style your opponent went for vs what cards you have and adapt your course accordingly.
They did X so I am better off to do Z now etc.
They are doing Y which means if I try to do X they will probably break my chain
