旗印

各クリーチャーはそれぞれ、それと共通のクリーチャー・タイプを少なくとも１つ持つ戦場にある他のクリーチャー１体につき＋１/＋１の修整を受ける。（例えば、ゴブリン・戦士が２体とゴブリン・シャーマンが１体戦場にあるなら、それらはそれぞれ＋２/＋２の修整を受ける。）

Coat of Arms

Each creature gets +1/+1 for each other creature on the battlefield that shares at least one creature type with it. (For example, if two Goblin Warriors and a Goblin Shaman are on the battlefield, each gets +2/+2.)

"Is that your coat of arms? Looks more like a shawl of branches to me!"
—Andreas the Imprudent, last words

Secret Lair Drop

"The rose is common in Legion heraldry. Thorns and petals tell of specific family achievements."
—Quintorius Kand, research notes

The Lost Caverns of Ixalan Commander

Each creature gets +1/+1 for each other creature on the battlefield that shares at least one creature type with it. (For example, two Vampire Clerics and a Human Cleric would each get +2/+2.)

The List

Duel Decks: Mind vs. Might

"Hup, two, three, four,
Dunno how to count no more."
—Mogg march

Tempest Remastered

If a creature has more than one creature type, and one of those types matches the creature you are calculating for, then count that creature. Only one type needs to match in order to get counted.

If you have a creature with more than one creature type, count all creatures which have either creature type.

Sharing multiple creature types doesn't give an additional bonus. Coat of Arms counts creatures, not creature types.
