Spell Golem
FIRE
Rank 1
Fiend/Xyz/Effect
2 Continuous Spell or Trap Cards + 1 Level 1 monster
While a monster is attached to this card, apply the effects of all attached Spell and Trap Cards as this card's effect. Once per turn, if this card would leave the field from your opponent's card effect, you can detach 1 Xyz Material from it instead. If this card is in Defense Position, banish it.

The last effect is Continuous and shouldn't have a colon.

This would get weird if you Overlaid, say, Safe Zone.

Overlaying Safe Zone would just mean that you'd have to get rid of this instead. I don't think there's any card that can target it and then be overlaid, but do correct me if I'm wrong.

Safe Zone didn't "leave the field".

Once it becomes a material, Safe Zone no longer applies its effect. Spell Golem now applies the effect, so if it leaves the field, the targeted monster is destroyed. Not sure how to word it in accordance with the card grammar, but that's what it's intended to do.
