From his hand, he has a triggered immediate effect that can be equipped to his monster as his Equip Spell with ATK 500 up, and an effect that allows him to search for a flame warrior other than a card with the same name or his Equip Spell at the end phase of the turn sent to GY
Now, on to the first set
Pikachu with Ash Again, Pikachu is the most popular Pokemon, and it can never hurt to include a Pikachu card in your collection
Against Steelsong decks its invaluable, it shuts down Ursula Deceiver of All singing on turn 4, stops Be Prepared on turn 7, and prevents A Whole New World being sung by Ariel Spectacular Singer
Besides the aforementioned Other Worlds, there's also some bureaucratic spaces on the board, including the Terror Track, and spaces for "Outskirts" (where extra monsters are placed), the "Sky" (where flying monsters go), and "Lost in Time & Space" (where unlucky investigators go)
A nice curve and applying constant pressure isnt quite as important as when playing Boros, but you want to make sure you have bodies on the board by turn 3
