I only know the second one. First, you summon the crystal beast in your hand. Then, you chain it and use torrental tribute. Third, you use crystal beast topaz tiger's effect. Fourth, you activate the card "crystal blessing" to put in your trap and spell place 2 crystal beast sapphire pegasus. Then, use crystal beacon to summon ruby carbuncle. Sixth, use ruby carbuncle's effect to summon all of your monsters in the trap and spell places. (you don't have to use sapphire pegasus' effect). Last, attack with all monsters.
