Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Once per turn, if an activated card effect tosses coins, immediately after it resolves, apply the following effect(s), depending on the number of heads. ● 1+: Inflict 500 damage to your opponent. ● 2+: Destroy 1 card your opponent controls. ● 3+: Look at your opponent's hand and discard 1 card from their hand. When an effect is activated that tosses a coin 2 or more times: You can banish this card from the GY; treat all results as heads.
