Special Summon "Star Boy" with "Water Hazard" and activate "Inferno Reckless Summon" to Special Summon 2 more "Star Boys". Activate "Wetlands" to give "Star Boy" an extra 1200 ATK and Normal Summon this card for a 3900 ATK direct attacker.
Or, instead, switch "Star Boy" and this card to have three 2900 ATK direct attackers to deal 8700 of direct damage in one turn.
With this card, "Cryomancer of the Ice Barrier" and "Wetlands" on the field, you've locked the opponent's monsters but are able to attack for 2400 damage each turn.
