FREE: Yugioh progressive auction

The listing, Yugioh progressive auction has ended.

Hey everyone! This is my first auction on here, and I'm hoping everything goes pretty smoothly. I've been looking around at other auctions to get a pretty good idea of how to list these cards, so here's hoping for the best.

This auction will start as a bid on one random holo card from my collection.

For every 100 credits in the final bid, I will add a random common from my collection.
For every 500 credits in the final bid, I will add 1 random rare from my collection.
And for every 1500 credits in the final bid, I will add another holo from my collection into the auction.

All rares added will either be silver lettered, black lettered, starfoil, mosaic rare, shatterfoil, or duel terminal.
All holos added will NOT be random bulk from hidden arsenal, number hunter, or dragons of legend.

Since this is my very first auction, the winner will also receive a special bonus! Which I will keep a secret until the auction is ended.

If you have any questions, please feel free to ask.

Thank you and happy bidding!
