Simultaneous Effects Go On Chain is when multiple flip, trigger, or trigger-like effects try to activate at the same time, for example, mystic tomato attacking mystic tomato. When this happens, the effects form a special chain, The chain goes like this:
1.Turn Player's Mandatory Effects
2.Non Turn Player's Mandatory Effects
3.Turn Player's Optional Effects
4.Non-turn Player's Optional effects
Let's take a look at what i think is a really good example, Say Neo-Spacian Grand Mole attacks Ally of Justice Catastor. What happens? Well
Catastor is Chain link 1 since it is non turn player mandatory effect (it goes off first)
Grand Mole is Chain link 2 since it is Turn player's optional effect (It goes off second)
So we make a chain with the above link order and since it resolves backwards, grand mole returns to hand and catastor to the extra deck.
Some notes:
- In the TCG effects activate first in the order they were triggered.
- In the OCG this does not apply. it just follows the order in SEGOC.
And here's a test i found that would help you become better at this chain stuff.
- Spoiler:
That's just about it with segoc, remember the chain order and your disputes with chains should be much easier to resolve.
