The first lets you search for Miracle Fusion upon Special Summon, and while Miracle Fusion can be searched with generic Fusion searchers, it’s nice for HEROs to have a Miracle Fusion searcher that’s in theme. It also has two hard once per turn effects.
All monsters you control gain 200 ATK for each different Attribute you control, which is fitting in HERO Decks you’re likely playing this in since you’re likely playing a plethora of different Attributes if not all 6. It must be Fusion Summoned, which is just like most to all the HERO Fusions. The summoning requirements are any 2 HEROs with different Attributes, meaning you should be able to summon this in any HERO variant except for more pure Destiny HEROs. Fine ATK, but low DEF, and you got that LIGHT/Warrior combo that’s still good.
Sunrise is a Level 7 LIGHT Warrior Fusion with 2500 ATK and 1200 DEF. HEROs are known for their Fusions, so fitting we get a new Fusion with Elemental HERO Sunrise.
