神河当時 - 源獣と召喚酔い

Things to Know
（省略）
The other tidbits I have to share involve the Genjus, which have a lot going on even though they seem simple.

A Genju played on a land that has been in play since the beginning of your turn can be activated and attack right away. The land is becoming a creature, and it will not have summoning sickness since it began the turn in play, even though it was just a land at that point.

Conversely, if you play a Genju on a land you just put out earlier in the turn, that land will not be able to attack even if you animate it. Things that came into play this turn cannot attack.

If someone is attacking you with an animated Genju land and you Naturalize the Genju in the middle of combat, the land is still a creature until end of turn and is still attacking you (unlike, say, Living Terrain. The Genju is activated and lasts until end of turn no matter what, whereas Living Terrain is static and lasts only as long as the land is enchanted). The same thing happens if you Naturalize the Genju in response to your opponent activating it. The best thing to do is to destroy the enchantment while your opponent is tapped out, or at the very least on your turn.

The last note on the Genjus involves a specific interaction--that between a Genju and Kiki-Jiki, Mirror Breaker. Say you activate Genju of the Spires, making a Mountain into a 6/1. You then copy that Mountain with Kiki-Jiki’s ability. Is the token a 6/1 creature with haste? No.

The token is a copy of Mountain, with haste. It is a land and can be tapped for mana, but it is not a creature and cannot attack. “Copy effects” copy cards as they are printed. Things like +1/+1 counters, type-changing effects (like the Genju), or temporary effects (like Jump) are not copied. So if you target a Mountain with Kiki-Jiki, regardless of what cool modifications you have made to that Mountain, you will get a token copy of a boring old Mountain, and you’ll still have to sacrifice it at the end of the turn.

『神河謀叛』のカードでルール的に注意すべき点を解説しています。

源獣でクリーチャー化する場合、そのターンに出した土地だと召喚酔いしているため、攻撃できないという点です。この点はうっかりしやすいのか、分かりやすさのためなのか、最近では土地をクリーチャー化する効果には速攻を付与するケースが増えました。特に、ニッサは土地のクリーチャー化がよく能力に登場しますが、たいてい速攻が付与されます。土地のクリーチャー化は緑に多く、速攻も緑は２番目に多いので、自然な調整でしょう。特に確証はありませんが、《古きものの目覚め/Awaken the Ancient》以降、この傾向があるように思います。

その他、クリーチャー化した後でエンチャントを破壊したケースや、《鏡割りのキキジキ/Kiki-Jiki, Mirror Breaker》でコピーしたケースについても触れられています。
