Stack Question

[Sgtlightbrite]

This occurred in a recent casual magic game and I was curious of the correct ruling....

Player 1 taps two forest to cast a creature spell

In response; Player 2 taps his Tidal Warrior to use it's activated ability and turn one of the lands into an island.

The actions go on the stack. What type of mana is produced?

1 blue & 1 green?

or

2 green?

[Yuwaki]

Player 1 will get 2 green mana, because Lands don´t use the stack.
The time player 2 taps his tidal warrior is the green mana already in player 1´s mana pool.

Mikuyume is right, mana abilities don't use the stack. (this goes for any ability the only generates mana, e.g. llanowar elfs, not just lands)

You might also want to note that a player can (and usually does in tournament play) tap the land during the casting of the spell, so you would only be able to respond after the spell is on the stack, not before.

How does this work in regards to other activated abilities. For example:I tap my Lightning Crafter to deal three damage to a creature. In response, my Lightning Crafter gets targeted by Lightning Bolt. Do both effects go on the stack and both die? or does the crafter die first and prevent the other damage effect?

You tap Lightning Crafter, placing its ability on the stack. In response, your opponent casts Lightning Bolt, placing it on the stack above the ability from Lightning Crafter. Last in first out: Lightning Bolt resolves, dealing three damage to Lightning Crafter, which dies due to state based effects. Next is the ability from Lightning Crafter, which resolves and deals three damage to the creature you targeted.
