My advice? Stop wasting your time with this. You have far more relevant things to devote your resources to.

Within the game or within life in general? 

Within the game, clearly.

Arena is an endgame exercise. You're far from it. Do the best you can with what you have, but don't waste silver/etc on this. Spend those resources getting dungeons/hydra/dt/dth/twins/etc progressed.

I completely disagree that it is an end game exercise. There is plenty of fun to have in the lower levels of arena. That is why the lower levels exist. 

Does immunity work against bombs?

Yes. You can use Immunity sets, or a cleanser like Skytouched, Hakkorhn, or Maus Mage to remove them and place Block Debuffs to prevent their reapplication.

I have never really looked at Skytouched's kit. Interresting but your team better be designed to only nee the A2 once. The passive is horrendous and even fully booked the A2 is on a 4 turn cooldown. I suppose that is good though because it would get really really frustrating if you could build her to constantly keep up the A2. Basically she is a fire and forget champion.  

I think that Hakkorhn is probably the safest pick because it cleanses and applies a block debuff for more than one turn with the same action. At least in this predicament where you facing a bomb opponent and you are not fast enough to go first. You just want to make sure that he is your fastest champion. 

I think with this information I can probably come up with a good go 2nd team against a bomb team and have some success. 

Thank you for the help.

Sorry but since you pulled Marichka your views on bombs are irrelevant.  See also poisons and HP burn.

So, like, I want to divert this conversation back to a point the OP made earlier. While it's fair to say "let's just play the game we can", and if it's fun to try to succeed in arena at an early stage, great, but I really want to emphasise two points:

1) It can get expensive very, *very* quickly. We're not talking just spending silver on upgrading gear - which is very expensive in and of itself. The rabbit hole that OP is looking to explore will, in short order, start involving gems for masteries, and then books for skills. And very shortly from there, it becomes "well this team didn't quite work, so who else can I try to swap out", and let's just continue this exercise until suddenly we're out of resources.

2) While doing all of that, those resources are not being spent in places that actually help progress. This is a game of exponentially-growing resources, and just like the whole "compounding interest" argument (that I particularly despise because of how simplistic it is), every time you waste something now, your longer-term returns are cut back ever more.

So if you really want to play the "let's see what happens" game, just try to do so with as little resource-investment as possible.

It's quite possible to explore team ideas without needing to invest deeply in them. For example, yes, booking that skill may take it from a 5-turn cooldown to a 3-turn one. But in an arena fight? You're almost never getting a chance to use the skill twice to begin with, and, even in the situations where you are, you'll be able to figure out if the team works long before you need to think about that. 

Same goes for those skills that go from 75% chance to land to 100%. Like - yes, you want to be at 100% because you don't want to lose a fight to a weighted coinflip. But you can see how the team works without needing to do that. Then, if it does, you can consider if it's actually worth investing in.

This is all true stuff. And I am a big fan of saving resources and playing for the long game....within limits though.

My counterargument is simple. It's a game. If you are having fun with something in the game, while disliking some other part of the grind, you shouldn't deprive yourself of the fun in favor of some goal 12 months away... or 6 even.

Games should be fun. Winning is fun, and playing smart with your resources helps future winning.... but telling people not to do something they enjoy in favor of slightly better long term progress is, im my humble opinion, against the spirit of playing a game to begin with.

Could not agree more, and I certainly was closer to kram's approach for the longest time while playing (hello never skipping advanced quests).

I think the risk of sucking the joy out of playing the game is too high. being worried about min/max'ing everything ALL the time just gets isn't a very fun place to be and can be tiring at best. 

There's always going to be optimal approaches and such, but I think it's fine - if not great - that others have differing approaches. 

A slight bit of nuance I'd like to counterpoint.... the optimal approach is playing the game in whatever way you find most fun. That is different for you versus Krama versus OP.
