If this face-up Fusion Summoned card is destroyed by battle, or leaves the field because of an opponent's card effect while its owner controls it: You can Special Summon 1 "Amazoness Queen" from your hand, Deck, or GY
Now, the same is true of running out a 2/3 flier in that ideally you want to be doing something better but it is proactive and it is known
Once you reach Mythic you will not go down to the Diamond Rank and you will stay there until season reset
But, ultimately, fans wanting to collect every single card in both variants have a hunt ahead of them, but hopefully, this check list helps
Majestic Absorption X SPELL Target 1 "Stardust Dragon", or 1 Synchro Monster that mentions it, that you control, then activate 1 of these effects
The latter is most likely to need recursion en-masse like this as they are minus-ing abilities and getting attacked to death
