I'm still learning the basics of Magic the Gathering; I was able to get some used cards in order to build my first deck, and I am thinking about building a green/white deck. One of the cards I got was Selesnya Guildgate, and had the following description:
Selesnya Guildgate enters the battlefied tapped.
(tap) Add [green] or [white] to your mana pool.
I have a couple of questions on how to use it properly given the following scenario:
- Is it a colorless land? It doesn't have any specific color at the right top
- If I use Selesnya, can I cast either Gladecover Scout or Champion of the Parish at that moment since they only required one mana?
- Since Selesnya enters tapped, the ability will be triggered to add either a green or white mana. Does that mean I can search for a land from my library and then add it to my mana pool? Or does it mean that if I would have another land in my hand (given this example, I don't have one), would I have added to my mana pool? I think I've seen ability cards saying "search for a land from your library" or similar... but for Selesnya, it doesn't specify.
