I have read up on this but I am unsure if its fully clear to me.
Could someone confirm or correct me?
Or possibly explain a bit more or direct me to recommendable explanation sites?
So far I understand it as:
Only optional effects can miss.
You can recognize them by having "when..you can.." written.
Does not apply to non optional "when".
They miss if they are not last in the chain.
For example tributes and econ on Botanica girl.
This is correct?
Am i "missing" anything? :P
The reason why people specify it has to be "the last thing to happen". Is because there are some events like the summon of monsters that don't start a chain that also affect activation timing. Say you tribute Peten for another monster? Last thing to happen was the tribute summon so Peten misses his activation timing.
Optional effects "when... you can..." can miss the timing of activation, in this case its activation requirements need to be the last thing to happen, if they don't, then it misses the timing.
E.g.: Botanical Girl has an optional effect "when", its activation requierements are reached when it is sent from the field to graveyard, but when this card is tributed for a tribute summon, the last thing to happen is the monster being summoned, so Botanical Girl misses the timing of activation.
Mandatory effects and optional effects "if" never miss the timing, they will be activated in the first opportunity possible.
you have to chain that card that you want to activate to chain link 1 or else the effect wont activate had to learn this the hard way
