#Yuriko first time deckbuilding a coherent deck
simple solstice
Im new to mtg and tried to come up with a yuriko deck and idk if im missing a key component to deckbuilding on this one. So please tell me what i can do to make this better
next sierra
Could you post a link to the decklist? It's hard to read the cards in this screenshot

I run Yuriko, I'd be happy to help, but yeah, need a link to the decklist because I can't read the picture either.
Fireshrieker isn't really that necessary/efficient, you'd be better off with say an enchant/equipment that made a creature to be unblockable to guarantee Yuriko and other ninja abilities to trigger. Doublestrike won't let you trigger if you are blocked.
[[Higure, the still wind]] would help you fetch ninjas and make ninjas unblockable
quasi hornetBOT
Legendary Creature — Human Ninja
Ninjutsu 
(, Return an unblocked attacker you control to hand: Put this card onto the battlefield from your hand tapped and attacking.)
Whenever Higure, the Still Wind deals combat damage to a player, you may search your library for a Ninja card, reveal it, put it into your hand, then shuffle.
: Target Ninja creature can't be blocked this turn.
3/4

Examples would be [[Whispersilk Cloak]], [[Invisibility]], [[Aqueous Form]]
quasi hornetBOT
Artifact — Equipment
Equipped creature can't be blocked and has shroud. (It can't be the target of spells or abilities.)
Equip
Such cloaks are in high demand both by assassins and by those who fear them.

[[Smoke Shroud]] is also useful since you can enchant it to a ninja for free upon ETB when it is in your graveyard

This does work with ninjitsu. Say you have it enchanted on a creature, and you ninjitsu it out for a ninja, Smoke Shroud hits the graveyard before the ninja ETBs so it can then be moved to the ninja immediately.
Leveler is a good combo to win with Jace, but it detracts from the theme of the deck. I'd consider cutting both unless you are decking yourself normally then keep Jace.
Covert Technician is kind of weak, you will either be not triggering his ability because you don't have any in hand or will ninjitusing him out for better ninjas as you get them in hand.
[[Satoru Umezawa]] let's you cycle through your deck faster to get the cards you need
quasi hornetBOT
Legendary Creature — Human Ninja
Whenever you activate a ninjutsu ability, look at the top three cards of your library. Put one of them into your hand and the rest on the bottom of your library in any order. This ability triggers only once each turn.
Each creature card in your hand has ninjutsu 
.
2/4

Also keep in mind, if you have Silver-Fur Master out, Tetsuko is going to be invalidated. And the -1 ninjitsu cost really isn't going to help when you won't normally be using ninjitsu more than once in a turn anyway
[[Deepchannel Mentor]] is a bit expensive cmc, but makes most of your creatures unblockable
