Cards you should get
[UR] Sacred Phoenix of Nepthys
★8/FIRE/Winged-Beast/ ATK 2400/DEF 1600
During your next Standby Phase after this card was destroyed by a card effect and sent to the Graveyard: Special Summon this card from the Graveyard. When you do: Destroy all Spell and Trap Cards on the field.
This card is treated as a Normal Monster while face-up on the field or in the Graveyard. While this card is face-up on the field, you can Normal Summon it to have it become an Effect Monster with this effect.● Once per turn: You can Special Summon 1 Zombie-Type monster from your hand or from either player's Graveyard. When this card leaves the field, destroy all Zombie-Type monsters Special Summoned by this card's effect.
You can substitute this card for any 1 Fusion Material Monster, but the other Fusion Material Monster(s) must be correct. You can Tribute Fusion Material Monsters on the field, including this face-up card; Special Summon 1 corresponding DARK Fusion Monster from your Extra Deck.
Since a "Naturia" monster activated its effect this turn, you can special summon Naturia Hydrangea.
Naturia Hydrangea effect- If the effect of a "Naturia" monster you control was activated during this turn, you can Special Summon this card from your hand.
Activate [Fire King Island once you have a faced up "Fire King" monster, destroy 1 monster in your hand or you control, and if you do, add 1 "Fire King" monster from your Deck to your hand.
Add Fire King Avatar Yaksha to your hand from your deck, to activate its effect "If a face-up "Fire King" monster you control is destroyed by a card effect (except during the Damage Step): You can Special Summon this card from your hand."
Among the mini boxes, this is one of the better and worthwhile ones to get. Sacred Phoenix is good, plus you get a ton of good staple cards and monsters in the box too. SRH, TTD, and Naturia's are a really good budget deck to play
Servant of Kings, Dawn of Destiny and Echoes of Silence are the best of the mini packs.
Honourable mention to Blades of Spirit.
I doubt there's someone more unlucky or hated by Komoney than me. I tried to be F2P but already realized that it is impossible, there is a scheme that makes it impossible,
they even reduced the gems of the legendary duelists and those at the back of the screen. I quit, good luck to those who stay.
