"Soft" Once per Turn

ATK:
2400
DEF:
3000
2 Level 5 or higher "Gladiator Beast" monsters Must first be Special Summoned (from your Extra Deck) by shuffling the above cards you control into the Deck. (You do not use "Polymerization".) Cannot be used as Fusion Material. Once per turn: You can Special Summon 1 "Gladiator Beast" Fusion Monster from your Extra Deck, except "Gladiator Beast Tamer Editor", ignoring its Summoning conditions.

ATK:
3000
DEF:
3000
2 Level 12 monsters Once per turn, if an Xyz Monster battled this turn, you can also Xyz Summon "Divine Arsenal AA-ZEUS - Sky Thunder" by using 1 Xyz Monster you control as material. (Transfer its materials to this card.) (Quick Effect): You can detach 2 materials from this card; send all other cards from the field to the GY. Once per turn, if another card(s) you control is destroyed by battle or an opponent's card effect: You can attach 1 card from your hand, Deck, or Extra Deck to this card as material.
- In your Extra Deck there are many copies of Zeus and on the field there are more than 1 Xyz monster fought => You can sum more than 1 copy of Zeus onto the field (unfortunately, it is limited to 1 so this dream can temporarily put aside)
- If Zeus has used a second effect (attach card) and Zeus has left the field, and you can manage to summon Zeus back to the field, for example using Monster Reborn . That second effect can still be used again .
Hard Once per Turn
There are also some differences between "This" and "Each".
- "This" means that the effect is only Hard Once per Turn while another effect can be used multiple times in the same turn, like Auram the World Chalice Blademaster or Marincess Marbled Rock .
- "Each" means you can use all of that card's effects in one turn but only once in that turn, a lot of cards have that card's effect so there won't be an example needed here

Other "Hard" Once per Turn types
- Hard Once per Turn between both effects: This often happens in some cards with 2 or more effects . Its notables are the same as regular Hard Once per Turn, except that it has "effect 1 *card name* per turn" instead of "this effect/per turn of" and also has the following clause "and only once that turn" . This means that in addition to Once per Turn, even if a card has 2 or more effects, you are only allowed to use 1 effect of that card in 1 turn, and must wait until the next turn to use the remaining effect. Some examples are Swordsoul Grandmaster - Chixiao , Appliancer Vacculephant or Elemental HERO Shadow Mist
- "You can only activate 1 *card name* Once per Turn" . There's no difference, except that these are Spell/Trap cards. However, there is a special case where you can activate multiple copies of a card with this restriction, we will talk about this case in the next article.
Swordsoul Grandmaster - Chixiao (For example)
