Here's a breakdown of some scenarios:
1. Effect Monsters with Summoning Conditions:
* Many monsters have effects that trigger when they attack.
* Some of these effects allow you to summon other monsters from your hand, deck, or graveyard.
* Example: "When this card attacks, you can Special Summon 1 "Cyber Dragon" from your hand."
2. "On Summon" Triggers:
* Some monsters have effects that activate "when this card is Summoned".
* You can potentially use these to summon other monsters *during* your opponent's turn if you can summon your monster during their turn (like with a "Quick-Play" Spell).
3. "After Battle" Effects:
* Some monsters have effects that activate after a battle phase, even if they didn't attack.
* This can indirectly allow you to summon a monster.
* Example: "After this card battles, you can Special Summon 1 Level 4 or lower monster from your hand."
Important Considerations:
* Summoning Conditions: Always check the specific card text for the conditions that must be met to summon the monster. There are often limitations (e.g., certain card types, levels, attributes).
* Timing: You may need to trigger the summoning effect during a specific phase of the game.
* Card Types: There are different types of cards that can summon monsters (e.g., spells, traps, monsters).
To get a definitive answer, you need to specify the specific card you are asking about. You can find information on individual cards on the official websites for the card game you are playing.
