I’ve been on the lookout for IF since the last one – Is it gone forever? I was really looking forward to playing it again.
Well, we still get OGW 1 & 2, so hopefully nothing is gone forever…
… except old NoP of course 
We’ll soon be getting a new weekday event (with the colour cycling each day) that allows us to play our best decks and potentially even be challenged by the stacked AI we’ll be facing (AI-only Enrage/Supercharge/Legendary). I think old NoP can rest in peace.
I’ve been wondering that myself. I was thinking they might do a second round of IF where they lock in Saheeli, Ajani2, and Tezz2 (presuming we get them.) If so, then in theory we wouldn’t see an IF until Saheeli is available for crystals. Next week or the one after, perhaps?
The previous IFs had been spaced at least 3 weeks apart heralded by the release of a new pw for each. Its safe to bet that there are at least 2 more IFs
