敵意に満ちた者、タイヴァー

あなたがコントロールしている１体以上のエルフが攻撃するたび、ターン終了時まで、それらは接死を得る。
あなたがコントロールしているすべてのクリーチャーは「このクリーチャーのマナ能力が解決されるたび、これの上にこのクリーチャーが生み出したマナの点数に等しい個数の＋１/＋１カウンターを置く。この能力は、毎ターン１回しか誘発しない。」を持つ。

好战不休泰瓦

每当由你操控的一个或数个妖精攻击时，它们获得死触异能直到回合结束。
每个由你操控的生物均具有「每当此生物的法术力异能结算时，在其上放置若干+1/+1指示物，数量等同于此生物产生的法术力数量。此异能每回合只会触发一次。」

Tyvar the Bellicose

Whenever one or more Elves you control attack, they gain deathtouch until end of turn.
Each creature you control has "Whenever a mana ability of this creature resolves, put a number of +1/+1 counters on it equal to the amount of mana this creature produced. This ability triggers only once each turn."

March of the Machine: The Aftermath

If Tyvar leaves the battlefield and returns to the battlefield in the same turn, or if Tyvar leaves and another Tyvar appears, the triggered ability granted by the new one is different than the triggered ability granted by the old one. The one granted by the new Tyvar may trigger for each creature you control, even if the ability granted by the old Tyvar triggered for those creatures that turn. (Note that creatures you control won't have the ability granted by the old one anymore, and if you control multiple Tyvars, you won't have the opportunity to activate mana abilities before the "legend rule" gets you down to one Tyvar.)

If the mana ability that caused the granted triggered ability to trigger was activated while casting a spell or activating an ability, the triggered ability will resolve (and +1/+1 counters will be added) before that spell or ability.

The ability that Tyvar grants to each creature you control functions independently for each creature. Specifically, the ability can trigger once each turn for each creature you control, not just once total.
