I was going to say 0%, but probably more like 0.1%

I would think you will get another swing or two, but not guarantee. 

I'm just a little curious honestly because they never mentioned Fatalis was going to be a guarantee event like Deck. That will leave just 1 single champ that is unobtainable through a guaranteed method, so I'm kinda thinking closer to like a 30% chance they run one for Archer. 

Tough to say.  I'm hopeful but odds are I won't have the resources anyway.

I'm holding onto hope. I missed the Prism Summon for her, I've been stockpiling Sacreds for a 2x Sacred with a 15/20/25 Event. The Sacred event was 2x but it was for Alatreon (who I got from his event anyway) so I didn't pull.

Now I'm really nervous. I can use a lot of Sacreds to get Fatalis (who I'm not big on anyway) OR I can put my faith in Plarium to do an event... Unfortunately Plarium seems to have a Hurt/Heal relationship with its' Playerbase but I'm holding onto hope anyway. It's called faith for a reason...

I have resources allocated for Archer if Plarium gives us a guaranteed chance.   

This is just my personal opinion, but Id hold for the Archer.  Even if they don't end up doing an event for her I really don't think you're missing much not getting Fatalis.  Unless you want him purely for collection purposes. 

What you got saved?  I'm so low on shards I'm screwed if it's anything but a grind able event.

9094 gems, 25m silver, too many brews

Waiting less patiently with each passing day.   lol

I read a post on Reddit that pointed out the only in-game event we've not had for the new champs is through a tournament leaderboard. So, the archer as a tournament reward for the top player in each group? Considering how the collaboration events so far have been only for krakens and end game players that wouldn't surprise. So you might get your wish, but not how you'd like it. :)

When does the chance to get Archer end?

Early next month, in March 

My possibly too cynical view is that there will be several progressive events for her. Then just before the collaboration ends there will be an expensive, shard-based event for her. It will be the final chance to monetize her, so the financial incentive will be totally in favor of it.  I think shard-based because that would generate more revenue than a grinding event.

I agree that we will probably have a guarrantee for her right before it ends. Since we have the "Collect'em all quest" for them. Normally we get a chance to acquire them based on the previous Collect'em all events. One that also has her soul kinda like Alatreon. Then the only souls we are missing for the MH I think they haven't done yet are Rathalos and Fatalis. The soul from the upcoming Hero's Path I can see being a MH soul. Would be weird if Wight Queen's soul is in there when people don't have her yet, but since it is at the end of the event to summon her I guess could toss her soul in there.
