Magic the gathering, two questions about two cards,?

Question

ok. quirion dryad, gets a +1/ +1 counter for each white/blue/red or black spell. so if i were to bring out say rakdos guildmage would that give me 2 +1/+1 counters??

and. master warcraft, could you just let certain attackers thre or must everyone of the attackers have a blocker?

many thanks.

Answer 1

On quirion dryad, the ability will only trigger once, even if the spell have multiple colors. So casting your guildmage will only add 1 +1/+1 counter to the dryad. (you can also see this in gatherer 04/2004).

On master warcraft you have complete control over choosing attackers and blockers; this means that some creatures can neither attack or block, depending on your choices.

Here are the precise rulings about this card (they clarify the interacction of master warcraft with planeswalkers):

4/1/2008 If the defending player controls a planeswalker, the person who played Master Warcraft first chooses the complete group of creatures that are going to attack. Then, for each of those creatures, the active player chooses who or what it's going to attack.

1/1/2006 You can decide that a creature won't block.

10/1/2005 You choose attackers and make blocking assignments regardless of whether it's your turn and regardless of whether the creatures are attacking you. Your choices must be legal within the normal rules for attacking and blocking.

10/1/2005 If an additional combat phase has been created, you may, if you choose, play Master Warcraft after attackers have been declared during the first combat phase but before attackers have been declared during the second one.

Good Luck
