Runed Crown is another way to get a rune onto the battlefield quickly, though its not as good
You can go all in on samurai, push for a heavy equipment theme, or build a straightforward combo deck featuring Helm of the Host
Its the first trading card game (TCG) and created a huge secondary market for rare and valuable cards
In the mid and late game, it becomes the best card in any deck running it
This activated ability is used when the card is in your hand, a bit like cycling or channel
I also give Nahiri, Forged in Fury points for being a legendary creature version of a planeswalker where it would make sense mechanically to include all of that characters planeswalker cards, and where you can actually do that within its color identity *cough cough* Ajani *cough*
