This card works well with "Gottoms' Emergency Call" since it helps maintain field presence. Also works with "Saber Hole" since it also requires a face up "X-Saber" monster.
If you control this card and an "X-Saber Axel", you could suicide this card into your opponent's monsters to summon another "XX-Saber Emmersblade", and repeat to draw overall three cards.
It is often a good idea to suicide this card so you can make quicker plays in an "XX-Saber" deck, as its effect will not work if your opponent suspects it and thus destroys it with a card effect come their turn. Also, it will give you faster access to your Synchro plays.
Another good strategy is to suicide this card, then summon another copy of it and suicide that one to summon a Tuner such as "X-Saber Pashuul" or "XX-Saber Fulhelmknight". Now, you will have two monsters in your Graveyard to activate "Gottoms' Emergency Call", and by bringing the two Emmersblades back, you can get even more monsters out of your deck.
