Great Job with the booster crafting! Now if we can just fix the glitch with Hazoret’s Undying Fury 
What glitch?
@Phillmoore If you have one other spell other than HUF, it glitches. Here’s what happens.
If you have played no copies of intended spell you seek before HUF, you will get all four copies.
If you played one spell already, the HUF will only pull three copies of that card when it should pull four.
If you played two copies already, then HUF will only pull two copies of that card when it should pull four.
If you played three prior HUF, you get one when you should get four.
If you played four prior HUF, You will get four. (it is believed that HUF is looking for library limits of 4 then resets after said cards are played)
otherwise HUF plays normally and without a glitch if you add additional spells.
But the point of it is to have one other card like approach of the second sun and play this one multiple times. Ok. Will wait to hear glitch sorted.
Sorry. Off topic
Strange. From my perspective it’s always fetch 4 spells no matter how many I’ve casted/exiled. It works that way since 2.3.
Panharmonicon has suffered from a similar “bug”. If you only have Omni in your deck other than pan, then play pan and Omni in succession, it will only fetch Omni until the last of the original 4 Omni have been pulled. There is no trigger on pan to auto generate the next deck if no supports are available during that loop.
in 2.3 HUF seems to work like the card says…
