If you are a Medium Ham patron or above you will have received the final Haikyuu collectible illustration this month. If you're a recent Medium Ham+ patron and might be looking to request past packs for the whole set, the above guide shows which monthly pack each illustration is in.
And if anyone else might be interested in getting these patron exclusives, you can switch to the Medium or Royal Ham tiers this April to receive the MAR'21 collectible right away, and request 1 or 2 past packs respectively as well.
The new collectible set starting this month will be Dorohedoro as was voted for by Medium Hams and up.

The first Dorohedoro collectible will be in the upcoming April pack, which will be available at the start of May. I will make another announcement then in case anyone might want to switch tiers for the start of the new set.
