Road to Kyoto '15 - 20/2/15

Today is the first official day I'm starting with preparations towards GP Kyoto.

I haven't played Legacy for a few months ever since the dreadful Treasure Cruise which game people access to 4x Ancestral Recall. I did not want to play in a format that simply encouraged me to make plays that were the total opposite of what I had practiced over the years.
To say that that era was very uncomfortable would be a great understatement.
I couldn't beat it and I did not particularly want to join it so I stepped away.

Now, I'm on my way back into the format, figuring out what I want to use.
Currently, I am thinking about playing the following cards:

Deathrite Shaman
Tasigur, the Golden Fang
Monastery Mentor

A quick search on mtgonline's decks, shows some decks I want to use as references:

URW Young Pyromancer:

1 Grim Lavamancer
4 Stoneforge Mystic
3 True-Name Nemesis
4 Young Pyromancer

4 Brainstorm
2 Dig Through Time
4 Force of Will
3 Lightning Bolt
2 Spell Pierce
4 Swords to Plowshares
4 Gitaxian Probe
4 Ponder
1 Batterskull
1 Umezawa's Jitte

2 Arid Mesa
4 Flooded Strand
1 Island
1 Plains
4 Polluted Delta
1 Scalding Tarn
3 Tundra
3 Volcanic Island

Grixis Ver

1 Jace, the Mind Sculptor
3 Cabal Therapy
2 Innocent Blood
4 Gitaxian Probe
4 Ponder
4 Brainstorm
1 Counterspell
4 Dig Through Time
4 Force of Will
4 Lightning Bolt
3 Thought Scour

1 Baleful Strix
2 Snapcaster Mage
1 Tasigur, the Golden Fang
4 Young Pyromancer

2 Flooded Strand
1 Island
3 Misty Rainforest
1 Polluted Delta
3 Scalding Tarn
3 Underground Sea
4 Volcanic Island


And finally, a Shardless BUG deck:

2 Jace, the mind sculptor
1 Umezawa's Jitte
1 Baleful Strix
4 Deathrite Shaman
1 Scavenging Ooze
4 Shardless Agent
4 Tarmogoyf
1 Tasigur, the Golden Fang

4 Abrupt Decay
4 Brainstorm
4 Force of Will
4 Ancestral Visions
2 Hymn to Tourach
3 Throughseize

3 Bayou
1 Marsh Flats
3 Misty Rainforest
2 Polluted Delta
1 Scalding Tarn
1 Swamp
3 Tropical Island
3 Underground Sea
4 Verdant Catacombs

I want to take the Thoughtscour deck, replace bolts with swords, replace Young Pyromancer with some Monastery Mentor (maybe not 4), have a Cavern of Souls to cast uncounterable humans, add some Deathrite Shamans. I suspect that if I use the Young Pyromancer shell with Monastery Mentors instead, the showdown against Young Pyromancer should be easy with a simple trigger allowing each token to trump the elemental tokens. Perhaps I shouldn't be too greedy with Tasigur but I should just keep these at the back of my head while I think of how to execute the deck properly.
If I go the white route, I'd have to get some Tundras. (2 copies I guess... given my budget constraint)
