Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
You can Ritual Summon this card with "Dogmatikamacabre". If this card is Ritual Summoned: You can target 2 face-up monsters on the field; make 1 of those monsters gain ATK equal to the other monster's ATK. Level 8 or higher "Dogmatika" monsters you control cannot be destroyed by battle. If a monster(s) is Special Summoned from your opponent's Extra Deck (except during the Damage Step): You can look at your opponent's Extra Deck and send 1 monster from it to the GY. You can only use this effect of "White Relic of Dogmatika" once per turn.
