I've been trying this since yesterday and can't seem to get this effect straight. The effect is: 

When this card is Special Summoned from being banished, it gains the following effects: This card is unaffected by your opponent's monster card effects. Once per turn you can banish 1 monster on the field. 

I've been able to program the, not being able to banish until after it's special summoned 1st, but i can't even get the unaffected part straight. Can someone please help me with this?
