Hello o/, im building a kiln fiend deck over here and i got this dilema that i hope you guys could share some opinions. I just realized that i do not exactly need lightning bolts in my deck, and, in my opinion, i should give more slots to phyrexian spells. This is my list bellow with a few explanations: 

Creatures: 

4 delvers, 4 kiln, 4 Cyclops 

Spells: 

4 Apostle's Blessing (most of the decks will desperately try to remove your creature as soon as they can)  2 Dispels (another way to survive instant removals and trigger the kiln)  2 Mutagenic growth (a phyrexian spell that also gives +2/+2 wat?)  2 Gytaxian probe  2 shadow rift (sometimes i wanna unblockable and a draw)  2 artful dodge (sometimes i wanna unblockable and a 1 cmc flashback)  4 ponders, 4 preordains, 2 gushs (better cantrips, gush is hilarious by the way in this build)  3 temur battle rage (why not assault strobe? yes i know its cheaper, but i got only 4 chances to be unblockable without temur, which is part of the plan A: kill in the early game)  4 gutshots (this is the polemic point, why should i use lightning bolts? to kill blockers? i think i already got a lot of ways to deal with them, but:  a - lets suppose i have no trample/unblockable spell in my hand, only 1 or 2 gutshots, this is pauper, most of the early game creatures have 1 toughness   b - i have trample/unblockable spells in my hand, in this case im going to target the player with the gutshot, yes, just 1 dmg, but i not only did trigger the kiln like i still have mana to cast another spells, like a temur or an apostle's blessing). 

my lands are:  9 islands 6 mountains 2 terramorfics 

And this is my opinion, i ratter prioritize phyrexian spells and do a lot of damage to myself but have mana enough to kill at 3rd or 4rth turn than make the game last longer and lose the strength of the deck. 

ps.: i have 4 bolts but im running them in my goblins deck(which seems to need it more) and a set of it is pretty expensive in my country T_T(yeah im talking about paper).
