Bandit deck -which affinity and which card upgrade?

[Morgotheron25 1]

I saw this thread:

https://forum.skylords.eu/index.php?/topic/3104-the-bandits-guide-to-pve/

and this

https://forum.skylords.eu/index.php?/topic/6493-new-player-bandit-deck/

 

I have a problem with affinity., I don't know which I should choose?

Corsair green or purple? I know that Commandos are better than Banditos, but I have 2 squads vs 3. I see that green is more expensive is it worth to buy green instead of purple?

Bloodhorn - I choose purple instead of red, ok?

Nomad - I see that most people choose Nature, so I choose nature

Soulhunter - blue or purple?

Bandit Spearmen

Bandit Sorceress?

 

Also I should first buy upgrade for T1/T2 creatures or T3/T4? Upgrade III cost is very high I must spend a lot of gold, so I must choose

No I play only pve, maybe in the future pvp

Buy upgrades I for everything you use frequently first.
It is tempting to answer "T3/T4", however, it is crucial to upgrade your main units in early game (usually archers and T2 unit you spam), however, in late game T4 is what matters the most. I'd suggest not upgrading T3 too much, focus on T1,T2,T4.

You may want to farm some upgrades on Advanced or Expert maps (Advanced for II, Expert for III) so that you won't have to pay for them in gold (I suggest this particularly for ultrarare II III cards)

Just to throw in another, newer, Bandit deck guide, but this is expensive and adresses more to advanced players.

To your other questions:

Bloodhorn affinities are both great, purple does a great job, if not a better (supported with Disenchant)

Skip Corsair

Soulhunter is usually not played for its affinity, choose either. 

Skip Spearmen and Bandit Sorc
