Sky has recently gotten a deck of playing cards; why only now, I don’t know. But he is definitely fascinated with it, although there might be not many people that can play. (Flygrass Town is a bit weird.) He is particularly attracted by Poker hands.

0. Familiarize yourself with playing cards and Poker hands as linked above.
1. There are 30 cards used to form 6 Poker hands. These 30 cards are all cards from Eights to Aces (89TJQKA), and the Seven of Spade and Seven of Heart.
2. The resulting Poker hands are a Straight, a Flush, a Full House, a Four of a Kind, a Non-Royal Straight Flush, and a Royal Flush.
3. Both the Flush and the Straight Flush are composed of only red cards.
4. The Straight is composed of only black cards.
5. The Full House doesn’t contain Spades.

What are the hands?
