Fire Princess is the most important part of this deck's strategy, so do everything to try and get her as soon as possible.
Crystal Seer can search a card from the top of your deck and add it to your hand, always get Fire Princess if she is not yet in your hand. This is also a good way to stall if you are trying to set up an OTK.
Draw Sense: Fire guarantees that you draw Fire Princess if your LP is reduced by 1500. Just remember to activate the skill before you draw during your draw phase.
If you have Fire Princess on your side of the field, you can use healing cards to increase your LP and then damage your opponent with the effect of Fire Princess.
Goblin Thief Heals you 500 LP while also burning 500 LP from your opponent. With Fire Princess on the field this totals into 1000 points of burn damage.
Supremacy Berry heals you a lot of LP, but will most likely be useless during later on in the duel when your LP becomes so much higher than your opponent's. Although Supremacy Berry could be activated and also help you stall early in the duel.
Spell Absorption is a really good card to use in this deck. It automatically heals you everytime a spell card is activated, combined with the effect of Fire Princess you could do some really good damage and also discourage your opponent from using spell cards. And using healing spell cards will cause Fire Princess to activate her effect twice, once for the healing spell and once for Spell Absorption.
Well, it's hard to OTK in turn 1 without Duel standby. But, all you need is a super-lucky hand, and 5 cards: Your Fire Waifu, 2x Goblin Thief AND 2x Spell Absorption! And you're done! Straight 4500 DMG in 1 turn!
Unless they got spell negate trap card(s). Then, GG.
Not that different just more stally so I can draw more cards added a a shard of greed and a golden apple and got rid off the super rush headlong. Having more than 20 cards in your deck doesn't matter if you can draw fire princess with skill anytime you want
