New Volcanic & koa'ki meiru support cards

For those are been following this game. There are 2 new cards that supports old archetypes. This Blaze Accelerator magazine. it's a continuous trap card. 
This card name becomes tri-blaze accelerator while it's on the field. Durning either player's main phase: you can send 1 Volcanic card form your hand to the graveyard, if you do draw 1 card. You can only used this effect of blaze accelerator magazine once per turn. During either players main phase: You can banish this card form your graveyard to send 1 volcanic card form your deck to the graveyard.
Here is the new Koa'ki meriru card.
This is Koa'ki meriru overdose

This a Level 4 earth rock type ATK 1900 DEF 1200
During your end phase destroy this card unless you send 1 Iron core of koa'ki meiru form your hand to the graveyard or reveal 1 rock type monster form your hand. During either players turn: when your opponent would summon a monster(s): you can tribute this card to negate the summon if you do destroyed those monsters. 
What you guys think? I think they are good cards.

The Blaze Accelerator isn't that great; tbh Volcanics never knew what their strategy was in the first place, and this would give them more consistency if it hadn't been made a trap card.

Koa'ki Meiru card is completely eclipsed by Thunder King... although the fact that it can negate multiple monsters at once is nifty.

I am torn on the trap.
It is searchible, so that is neat, and it gives shell more pratical use as you add it, then pitch it.
The name also gives doomfire more play. Overal it is neat, and the draw during either players turn is equally neat, but Volcanic already have plus power, they need stall cards.
