it says that:
12/1/2004: The training counter just marks which creatures have been changed; an effect that removes the counter doesn't change the creature's types or abilities.
12/1/2004: Note that multiple instances of the bushido ability each trigger separately.
so every time it grants ability, it will remain forever(until the game ends
correction fix below(i tested this, need further testing i suppose):
- Code: Select all
[card]
name=Sensei Golden-Tail
auto=bushido(1/1)
auto={1}{W}{T}:name(train samurai) target(creature) transforms((,newability[bushido(1/1)],newability[counter(0/0.1.Training)],newability[this(cantargetcard(creature) becomes(Samurai) )])) asSorcery forever
text=Bushido 1 (When this blocks or becomes blocked, it gets +1/+1 until end of turn.) -- {1}{W}, {T}: Put a training counter on target creature. That creature gains bushido 1 and becomes a Samurai in addition to its other creature types. Activate this ability only any time you could cast a sorcery.
mana={1}{W}
type=Legendary Creature
subtype=Fox Samurai
power=2
toughness=1
[/card]
now, if you look closely on the third newability it has a check if the targeted card is a creature? why? (taken from wizards forum thread)
If the ability resolves, then the creature stops being a creature, later, Sensei Golden-Tail's effect will not end. (The ability checks whether the creature is a creature only at the time you activate it and the time it resolves.)
If the affected creature stops being a creature by some other spell or ability, Sensei Golden-Tail's effect will not end. If that permanent becomes a creature again, the bonuses that Sensei Golden-Tail's ability grants it, will continue to affect it when applicable.
Sensei Golden-Tail's ability does not stop working when the factory stops being a creature, though it does stop being a samurai when it stops being a creature (see 204.1a).
